Note the following details of the code protection feature on Microchip devices: * * * Microchip products meet the specification contained in their particular Microchip Data Sheet. Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. Microchip is willing to work with the customer who is concerned about the integrity of their code. Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable."

2.0 GUIDELINES FOR GETTING STARTED WITH 16-BIT DIGITAL SIGNAL CONTROLLERS
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "dsPIC33F Family Reference Manual", which is available from the Microchip website (www.microchip.com).
2.2
Decoupling Capacitors
The use of decoupling capacitors on every pair of power supply pins, such as VDD, VSS, AVDD and AVSS is required. Consider the following criteria when using decoupling capacitors: * Value and type of capacitor: Recommendation of 0.1 F (100 nF), 10-20V. This capacitor should be a low-ESR and have resonance frequency in the range of 20 MHz and higher. It is recommended that ceramic capacitors be used. * Placement on the printed circuit board: The decoupling capacitors should be placed as close to the pins as possible. It is recommended to place the capacitors on the same side of the board as the device. If space is constricted, the capacitor can be placed on another layer on the PCB using a via; however, ensure that the trace length from the pin to the capacitor is within one-quarter inch (6 mm) in length. * Handling high frequency noise: If the board is experiencing high frequency noise, upward of tens of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor. The value of the second capacitor can be in the range of 0.01 F to 0.001 F. Place this second capacitor next to the primary decoupling capacitor. In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the power and ground pins as possible. For example, 0.1 F in parallel with 0.001 F. * Maximizing performance: On the board layout from the power supply circuit, run the power and return traces to the decoupling capacitors first, and then to the device pins. This ensures that the decoupling capacitors are first in the power chain. Equally important is to keep the trace length between the capacitor and the power pins to a minimum thereby reducing PCB track inductance.
Note:
2.1
Basic Connection Requirements
Getting started with the dsPIC33FJXXXMCX06/X08/X10 family of 16-bit Digital Signal Controllers (DSCs) requires attention to a minimal set of device pin connections before proceeding with development. The following is a list of pin names, which must always be connected: * All VDD and VSS pins (see Section 2.2 "Decoupling Capacitors") * All AVDD and AVSS pins (regardless if ADC module is not used) (see Section 2.2 "Decoupling Capacitors") * VCAP/VDDCORE (see Section 2.3 "Capacitor on Internal Voltage Regulator (VCAP/VDDCORE)") * MCLR pin (see Section 2.4 "Master Clear (MCLR) Pin") * PGECx/PGEDx pins used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes (see Section 2.5 "ICSP Pins") * OSC1 and OSC2 pins when external oscillator source is used (see Section 2.6 "External Oscillator Pins") Additionally, the following pins may be required: * VREF+/VREF- pins used when external voltage reference for ADC module is implemented Note: The AVDD and AVSS pins must be connected independent of the ADC voltage reference source.

Master Clear (MCLR) Pin
The MCLR pin provides for two specific device functions: * Device Reset * Device programming and debugging During device programming and debugging, the resistance and capacitance that can be added to the pin must be considered. Device programmers and debuggers drive the MCLR pin. Consequently, specific voltage levels (VIH and VIL) and fast signal transitions must not be adversely affected. Therefore, specific values of R and C will need to be adjusted based on the application and PCB requirements.

For example, as shown in Figure 2-2, it is recommended that the capacitor C, be isolated from the MCLR pin during programming and debugging operations. Place the components shown in Figure 2-2 within one-quarter inch (6 mm) from the MCLR pin.
2.2.1
TANK CAPACITORS
FIGURE 2-2:
On boards with power traces running longer than six inches in length, it is suggested to use a tank capacitor for integrated circuits including DSCs to supply a local power source. The value of the tank capacitor should be determined based on the trace resistance that connects the power supply source to the device, and the maximum current drawn by the device in the application. In other words, select the tank capacitor so that it meets the acceptable voltage sag at the device. Typical values range from 4.7 F to 47 F.

2.3
Capacitor on Internal Voltage Regulator (VCAP/VDDCORE)
Note 1:
A low-ESR (< 5 Ohms) capacitor is required on the VCAP/VDDCORE pin, which is used to stabilize the voltage regulator output voltage. The VCAP/VDDCORE pin must not be connected to VDD, and must have a capacitor between 4.7 F and 10 F, 16V connected to ground. The type can be ceramic or tantalum. Refer to Section 26.0 "Electrical Characteristics" for additional information. The placement of this capacitor should be close to the VCAP/VDDCORE. It is recommended that the trace length not exceed one-quarter inch (6 mm). Refer to Section 23.2 "On-Chip Voltage Regulator" for details.
R 10 k is recommended. A suggested starting value is 10 k. Ensure that the MCLR pin VIH and VIL specifications are met. R1 470 will limit any current flowing into MCLR from the external capacitor C, in the event of MCLR pin breakdown, due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS). Ensure that the MCLR pin VIH and VIL specifications are met.

2.5 ICSP Pins 2.6 External Oscillator Pins
The PGECx and PGEDx pins are used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes. It is recommended to keep the trace length between the ICSP connector and the ICSP pins on the device as short as possible. If the ICSP connector is expected to experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of Ohms, not to exceed 100 Ohms. Pull-up resistors, series diodes, and capacitors on the PGECx and PGEDx pins are not recommended as they will interfere with the programmer/debugger communications to the device. If such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. Alternatively, refer to the AC/DC characteristics and timing requirements information in the respective device Flash programming specification for information on capacitive loading limits and pin input voltage high (VIH) and input low (VIL) requirements. Ensure that the "Communication Channel Select" (i.e., PGECx/PGEDx pins) programmed into the device matches the physical connections for the ICSP to MPLAB(R) ICD 2, MPLAB ICD 3 or MPLAB REAL ICETM. For more information on ICD 2, ICD 3 and REAL ICE connection requirements, refer to the following documents that are available on the Microchip website. * "MPLAB(R) ICD 2 In-Circuit Debugger User's Guide" DS51331 * "Using MPLAB(R) ICD 2" (poster) DS51265 * "MPLAB(R) ICD 2 Design Advisory" DS51566 * "Using MPLAB(R) ICD 3 In-Circuit Debugger" (poster) DS51765 * "MPLAB(R) ICD 3 Design Advisory" DS51764 * "MPLAB(R) REAL ICETM In-Circuit Emulator User's Guide" DS51616 * "Using MPLAB(R) REAL ICETM" (poster) DS51749 Many DSCs have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to Section 9.0 "Oscillator Configuration" for details). The oscillator circuit should be placed on the same side of the board as the device. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. The load capacitors should be placed next to the oscillator itself, on the same side of the board. Use a grounded copper pour around the oscillator circuit to isolate them from surrounding circuits. The grounded copper pour should be routed directly to the MCU ground. Do not run any signal traces or power traces inside the ground pour. Also, if using a two-sided board, avoid any traces on the other side of the board where the crystal is placed. A suggested layout is shown in Figure 2-3.

2.7 Oscillator Value Conditions on Device Start-up
If the PLL of the target device is enabled and configured for the device start-up oscillator, the maximum oscillator source frequency must be limited to 4 MHz < FIN < 8 MHz to comply with device PLL start-up conditions. This means that if the external oscillator frequency is outside this range, the application must start-up in the FRC mode first. The default PLL settings after a POR with an oscillator frequency outside this range will violate the device operating speed. Once the device powers up, the application firmware can initialize the PLL SFRs, CLKDIV and PLLDBF to a suitable value, and then perform a clock switch to the Oscillator + PLL clock source. Note that clock switching must be enabled in the device Configuration word.
2.8
Configuration of Analog and Digital Pins During ICSP Operations
If MPLAB ICD 2, ICD 3 or REAL ICE is selected as a debugger, it automatically initializes all of the A/D input pins (ANx) as "digital" pins, by setting all bits in the AD1PCFGL register. The bits in this register that correspond to the A/D pins that are initialized by MPLAB ICD 2, ICD 3 or REAL ICE, must not be cleared by the user application firmware; otherwise, communication errors will result between the debugger and the device. If your application needs to use certain A/D pins as analog input pins during the debug session, the user application must clear the corresponding bits in the AD1PCFGL register during initialization of the ADC module. When MPLAB ICD 2, ICD 3 or REAL ICE is used as a programmer, the user application firmware must correctly configure the AD1PCFGL register. Automatic initialization of this register is only done during debugger operation. Failure to correctly configure the register(s) will result in all A/D pins being recognized as analog input pins, resulting in the port value being read as a logic `0', which may affect user application functionality.
2.9
Unused I/Os
Unused I/O pins should be configured as outputs and driven to a logic-low state. Alternatively, connect a 1k to 10k resistor to VSS on unused pins and drive the output to logic low.

CPU
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 2. "CPU" (DS70204) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
3.1
Data Addressing Overview
The dsPIC33FJXXXMCX06/X08/X10 CPU module has a 16-bit (data) modified Harvard architecture with an enhanced instruction set, including significant support for DSP. The CPU has a 24-bit instruction word with a variable length opcode field. The Program Counter (PC) is 23 bits wide and addresses up to 4M x 24 bits of user program memory space. The actual amount of program memory implemented varies by device. A single-cycle instruction prefetch mechanism is used to help maintain throughput and provides predictable execution. All instructions execute in a single cycle, with the exception of instructions that change the program flow, the double word move (MOV.D) instruction and the table instructions. Overhead-free program loop constructs are supported using the DO and REPEAT instructions, both of which are interruptible at any point. The dsPIC33FJXXXMCX06/X08/X10 devices have sixteen 16-bit working registers in the programmer's model. Each of the working registers can serve as a data, address or address offset register. The 16th working register (W15) operates as a software Stack Pointer (SP) for interrupts and calls. The dsPIC33FJXXXMCX06/X08/X10 instruction set has two classes of instructions: MCU and DSP. These two instruction classes are seamlessly integrated into a single CPU. The instruction set includes many addressing modes and is designed for optimum C compiler efficiency. For most instructions, the dsPIC33FJXXXMCX06/X08/X10 is capable of executing a data (or program data) memory read, a working register (data) read, a data memory write and a program (instruction) memory read per instruction cycle. As a result, three parameter instructions can be supported, allowing A + B = C operations to be executed in a single cycle. A block diagram of the CPU is shown in Figure 3-1, and the programmer's model for the dsPIC33FJXXXMCX06/X08/X10 is shown in Figure 3-2.
The data space can be addressed as 32K words or 64 Kbytes and is split into two blocks referred to as X and Y data memory. Each memory block has its own independent Address Generation Unit (AGU). The MCU class of instructions operates solely through the X memory AGU, which accesses the entire memory map as one linear data space. Certain DSP instructions operate through the X and Y AGUs to support dual operand reads, which splits the data address space into two parts. The X and Y data space boundary is device-specific. Overhead-free circular buffers (Modulo Addressing mode) are supported in both X and Y address spaces. The Modulo Addressing removes the software boundary checking overhead for DSP algorithms. Furthermore, the X AGU circular addressing can be used with any of the MCU class of instructions. The X AGU also supports Bit-Reversed Addressing to greatly simplify input or output data reordering for radix-2 FFT algorithms. The upper 32 Kbytes of the data space memory map can optionally be mapped into program space at any 16K program word boundary defined by the 8-bit Program Space Visibility Page (PSVPAG) register. The program to data space mapping feature lets any instruction access program space as if it were data space. The data space also includes 2 Kbytes of DMA RAM, which is primarily used for DMA data transfers but may be used as general purpose RAM.
3.2
DSP Engine Overview
The DSP engine features a high-speed, 17-bit by 17-bit multiplier, a 40-bit ALU, two 40-bit saturating accumulators and a 40-bit bidirectional barrel shifter. The barrel shifter is capable of shifting a 40-bit value up to 16 bits right or left in a single cycle. The DSP instructions operate seamlessly with all other instructions and have been designed for optimal real-time performance. The MAC instruction and other associated instructions can concurrently fetch two data operands from memory while multiplying two W registers and accumulating and optionally saturating the result in the same cycle. This instruction functionality requires that the RAM memory data space be split for these instructions and linear for all others. Data space partitioning is achieved in a transparent and flexible manner through dedicating certain working registers to each address space.

3.3 Special MCU Features
The dsPIC33FJXXXMCX06/X08/X10 features a 17-bit by 17-bit, single-cycle multiplier that is shared by both the MCU ALU and DSP engine. The multiplier can perform signed, unsigned and mixed-sign multiplication. Using a 17-bit by 17-bit multiplier for 16-bit by 16-bit multiplication not only allows you to perform mixed-sign multiplication, it also achieves accurate results for special operations, such as (-1.0) x (-1.0). The dsPIC33FJXXXMCX06/X08/X10 supports 16/16 and 32/16 divide operations, both fractional and integer. All divide instructions are iterative operations. They must be executed within a REPEAT loop, resulting in a total execution time of 19 instruction cycles. The divide operation can be interrupted during any of those 19 cycles without a loss of data. A 40-bit barrel shifter is used to perform up to a 16-bit left or right shift in a single cycle. The barrel shifter can be used by both MCU and DSP instructions.

3.5 Arithmetic Logic Unit (ALU) 3.6 DSP Engine
The dsPIC33FJXXXMCX06/X08/X10 ALU is 16 bits wide and is capable of addition, subtraction, bit shifts and logic operations. Unless otherwise mentioned, arithmetic operations are 2's complement in nature. Depending on the operation, the ALU may affect the values of the Carry (C), Zero (Z), Negative (N), Overflow (OV) and Digit Carry (DC) Status bits in the SR register. The C and DC Status bits operate as Borrow and Digit Borrow bits, respectively, for subtraction operations. The ALU can perform 8-bit or 16-bit operations, depending on the mode of the instruction that is used. Data for the ALU operation can come from the W register array or data memory, depending on the addressing mode of the instruction. Likewise, output data from the ALU can be written to the W register array or a data memory location. Refer to the "dsPIC30F/33F Programmer's Reference Manual" (DS70157) for information on the SR bits affected by each instruction. The dsPIC33FJXXXMCX06/X08/X10 CPU incorporates hardware support for both multiplication and division. This includes a dedicated hardware multiplier and support hardware for 16-bit-divisor division. The DSP engine consists of a high-speed, 17-bit x 17-bit multiplier, a barrel shifter and a 40-bit adder/subtracter (with two target accumulators, round and saturation logic). The dsPIC33FJXXXMCX06/X08/X10 is a single-cycle, instruction flow architecture; therefore, concurrent operation of the DSP engine with MCU instruction flow is not possible. However, some MCU ALU and DSP engine resources may be used concurrently by the same instruction (e.g., ED, EDAC). The DSP engine also has the capability to perform inherent accumulator-to-accumulator operations which require no additional data. These instructions are ADD, SUB and NEG. The DSP engine has various options selected through various bits in the CPU Core Control register (CORCON), as listed below: 1. 2. 3. 4. 5. 6. 7. Fractional or integer DSP multiply (IF) Signed or unsigned DSP multiply (US) Conventional or convergent rounding (RND) Automatic saturation on/off for AccA (SATA) Automatic saturation on/off for AccB (SATB) Automatic saturation on/off for writes to data memory (SATDW) Accumulator Saturation mode selection (ACCSAT)
3.5.1
MULTIPLIER
Using the high-speed 17-bit x 17-bit multiplier of the DSP engine, the ALU supports unsigned, signed or mixed-sign operation in several MCU multiplication modes: 1. 2. 3. 4. 5. 6. 7. 16-bit x 16-bit signed 16-bit x 16-bit unsigned 16-bit signed x 5-bit (literal) unsigned 16-bit unsigned x 16-bit unsigned 16-bit unsigned x 5-bit (literal) unsigned 16-bit unsigned x 16-bit signed 8-bit unsigned x 8-bit unsigned
Table 3-1 provides a summary of DSP instructions. A block diagram of the DSP engine is shown in Figure 3-3.

3.5.2
DIVIDER
The divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: 1. 2. 3. 4. 32-bit signed/16-bit signed divide 32-bit unsigned/16-bit unsigned divide 16-bit signed/16-bit signed divide 16-bit unsigned/16-bit unsigned divide
The quotient for all divide instructions ends up in W0 and the remainder in W1. 16-bit signed and unsigned DIV instructions can specify any W register for both the 16-bit divisor (Wn) and any W register (aligned) pair (W(m + 1):Wm) for the 32-bit dividend. The divide algorithm takes one cycle per bit of divisor, so both 32-bit/16-bit and 16-bit/16-bit instructions take the same number of cycles to execute.

3.6.1 MULTIPLIER 3.6.2.1
The 17-bit x 17-bit multiplier is capable of signed or unsigned operation and can multiplex its output using a scaler to support either 1.31 fractional (Q31) or 32-bit integer results. Unsigned operands are zero-extended into the 17th bit of the multiplier input value. Signed operands are sign-extended into the 17th bit of the multiplier input value. The output of the 17-bit x 17-bit multiplier/scaler is a 33-bit value which is sign-extended to 40 bits. Integer data is inherently represented as a signed two's complement value, where the MSb is defined as a sign bit. Generally speaking, the range of an N-bit two's complement integer is -2N-1 to 2N-1 - 1. For a 16-bit integer, the data range is -32768 (0x8000) to 32767 (0x7FFF) including 0. For a 32-bit integer, the data range is -2,147,483,648 (0x8000 0000) to 2,147,483,647 (0x7FFF FFFF). When the multiplier is configured for fractional multiplication, the data is represented as a two's complement fraction, where the MSb is defined as a sign bit and the radix point is implied to lie just after the sign bit (QX format). The range of an N-bit two's complement fraction with this implied radix point is -1.0 to (1 - 21-N). For a 16-bit fraction, the Q15 data range is -1.0 (0x8000) to 0.999969482 (0x7FFF) including 0 and has a precision of 3.01518x10-5. In Fractional mode, the 16 x 16 multiply operation generates a 1.31 product which has a precision of 4.65661 x 10-10. The same multiplier is used to support the MCU multiply instructions which include integer 16-bit signed, unsigned and mixed sign multiplies. The MUL instruction may be directed to use byte or word sized operands. Byte operands will direct a 16-bit result, and word operands will direct a 32-bit result to the specified register(s) in the W array.
Adder/Subtracter, Overflow and Saturation
The adder/subtracter is a 40-bit adder with an optional zero input into one side, and either true, or complement data into the other input. In the case of addition, the Carry/Borrow input is active-high and the other input is true data (not complemented), whereas in the case of subtraction, the Carry/Borrow input is active-low and the other input is complemented. The adder/subtracter generates Overflow Status bits, SA/SB and OA/OB, which are latched and reflected in the STATUS register: * Overflow from bit 39: this is a catastrophic overflow in which the sign of the accumulator is destroyed. * Overflow into guard bits 32 through 39: this is a recoverable overflow. This bit is set whenever all the guard bits are not identical to each other. The adder has an additional saturation block which controls accumulator data saturation, if selected. It uses the result of the adder, the Overflow Status bits described above and the SAT (CORCON<7:6>) and ACCSAT (CORCON<4>) mode control bits to determine when and to what value to saturate. Six STATUS register bits have been provided to support saturation and overflow; they are: 1. 2. 3. OA: AccA overflowed into guard bits OB: AccB overflowed into guard bits SA: AccA saturated (bit 31 overflow and saturation) or AccA overflowed into guard bits and saturated (bit 39 overflow and saturation) SB: AccB saturated (bit 31 overflow and saturation) or AccB overflowed into guard bits and saturated (bit 39 overflow and saturation) OAB: Logical OR of OA and OB SAB: Logical OR of SA and SB
3.6.2
DATA ACCUMULATORS AND ADDER/SUBTRACTER
4.
The data accumulator consists of a 40-bit adder/subtracter with automatic sign extension logic. It can select one of two accumulators (A or B) as its pre-accumulation source and post-accumulation destination. For the ADD and LAC instructions, the data to be accumulated or loaded can be optionally scaled via the barrel shifter prior to accumulation.
5. 6.
The OA and OB bits are modified each time data passes through the adder/subtracter. When set, they indicate that the most recent operation has overflowed into the accumulator guard bits (bits 32 through 39). The OA and OB bits can also optionally generate an arithmetic warning trap when they and the corresponding Overflow Trap Flag Enable bits (OVATE, OVBTE) in the INTCON1 register (refer to Section 7.0 "Interrupt Controller") are set. This allows the user to take immediate action, for example, to correct system gain.
(c) 2009 Microchip Technology Inc.
DS70287C-page 31
dsPIC33FJXXXMCX06/X08/X10
The SA and SB bits are modified each time data passes through the adder/subtracter, but can only be cleared by the user. When set, they indicate that the accumulator has overflowed its maximum range (bit 31 for 32-bit saturation or bit 39 for 40-bit saturation) and will be saturated (if saturation is enabled). When saturation is not enabled, SA and SB default to bit 39 overflow and, thus, indicate that a catastrophic overflow has occurred. If the COVTE bit in the INTCON1 register is set, SA and SB bits will generate an arithmetic warning trap when saturation is disabled. The Overflow and Saturation Status bits can optionally be viewed in the STATUS Register (SR) as the logical OR of OA and OB (in bit OAB) and the logical OR of SA and SB (in bit SAB). This allows programmers to check one bit in the STATUS register to determine if either accumulator has overflowed or one bit to determine if either accumulator has saturated. This would be useful for complex number arithmetic, which typically uses both the accumulators. The device supports three Saturation and Overflow modes: 1. Bit 39 Overflow and Saturation: When bit 39 overflow and saturation occurs, the saturation logic loads the maximally positive 9.31 (0x7FFFFFFFFF) or maximally negative 9.31 value (0x8000000000) into the target accumulator. The SA or SB bit is set and remains set until cleared by the user. This is referred to as `super saturation' and provides protection against erroneous data or unexpected algorithm problems (e.g., gain calculations). Bit 31 Overflow and Saturation: When bit 31 overflow and saturation occurs, the saturation logic then loads the maximally positive 1.31 value (0x007FFFFFFF) or maximally negative 1.31 value (0x0080000000) into the target accumulator. The SA or SB bit is set and remains set until cleared by the user. When this Saturation mode is in effect, the guard bits are not used (so the OA, OB or OAB bits are never set). Bit 39 Catastrophic Overflow: The bit 39 Overflow Status bit from the adder is used to set the SA or SB bit, which remains set until cleared by the user. No saturation operation is performed and the accumulator is allowed to overflow (destroying its sign). If the COVTE bit in the INTCON1 register is set, a catastrophic overflow can initiate a trap exception.
3.6.2.2
Accumulator `Write Back'
The MAC class of instructions (with the exception of MPY, MPY.N, ED and EDAC) can optionally write a rounded version of the high word (bits 31 through 16) of the accumulator that is not targeted by the instruction into data space memory. The write is performed across the X bus into combined X and Y address space. The following addressing modes are supported: 1. W13, Register Direct: The rounded contents of the non-target accumulator are written into W13 as a 1.15 fraction. [W13]+ = 2, Register Indirect with Post-Increment: The rounded contents of the non-target accumulator are written into the address pointed to by W13 as a 1.15 fraction. W13 is then incremented by 2 (for a word write).

3.6.2.3
Round Logic
The round logic is a combinational block which performs a conventional (biased) or convergent (unbiased) round function during an accumulator write (store). The Round mode is determined by the state of the RND bit in the CORCON register. It generates a 16-bit, 1.15 data value which is passed to the data space write saturation logic. If rounding is not indicated by the instruction, a truncated 1.15 data value is stored and the least significant word is simply discarded. Conventional rounding zero-extends bit 15 of the accumulator and adds it to the ACCxH word (bits 16 through 31 of the accumulator). If the ACCxL word (bits 0 through 15 of the accumulator) is between 0x8000 and 0xFFFF (0x8000 included), ACCxH is incremented. If ACCxL is between 0x0000 and 0x7FFF, ACCxH is left unchanged. A consequence of this algorithm is that over a succession of random rounding operations, the value tends to be biased slightly positive. Convergent (or unbiased) rounding operates in the same manner as conventional rounding, except when ACCxL equals 0x8000. In this case, the Least Significant bit (bit 16 of the accumulator) of ACCxH is examined. If it is `1', ACCxH is incremented. If it is `0', ACCxH is not modified. Assuming that bit 16 is effectively random in nature, this scheme removes any rounding bias that may accumulate. The SAC and SAC.R instructions store either a truncated (SAC), or rounded (SAC.R) version of the contents of the target accumulator to data memory via the X bus, subject to data saturation (see Section 3.6.2.4 "Data Space Write Saturation"). For the MAC class of instructions, the accumulator write-back operation will function in the same manner, addressing combined MCU (X and Y) data space though the X bus. For this class of instructions, the data is always subject to rounding.

3.6.2.4 Data Space Write Saturation 3.6.3 BARREL SHIFTER
In addition to adder/subtracter saturation, writes to data space can also be saturated - but without affecting the contents of the source accumulator. The data space write saturation logic block accepts a 16-bit, 1.15 fractional value from the round logic block as its input, together with overflow status from the original source (accumulator) and the 16-bit round adder. These inputs are combined and used to select the appropriate 1.15 fractional value as output to write to data space memory. If the SATDW bit in the CORCON register is set, data (after rounding or truncation) is tested for overflow and adjusted accordingly. For input data greater than 0x007FFF, data written to memory is forced to the maximum positive 1.15 value, 0x7FFF. For input data less than 0xFF8000, data written to memory is forced to the maximum negative 1.15 value, 0x8000. The Most Significant bit of the source (bit 39) is used to determine the sign of the operand being tested. If the SATDW bit in the CORCON register is not set, the input data is always passed through unmodified under all conditions. The barrel shifter is capable of performing up to 16-bit arithmetic or logic right shifts, or up to 16-bit left shifts in a single cycle. The source can be either of the two DSP accumulators or the X bus (to support multi-bit shifts of register or memory data). The shifter requires a signed binary value to determine both the magnitude (number of bits) and direction of the shift operation. A positive value shifts the operand right. A negative value shifts the operand left. A value of `0' does not modify the operand. The barrel shifter is 40 bits wide, thereby obtaining a 40-bit result for DSP shift operations and a 16-bit result for MCU shift operations. Data from the X bus is presented to the barrel shifter between bit positions 16 to 31 for right shifts and between bit positions 0 to 16 for left shifts.

MEMORY ORGANIZATION
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 3. "Data Memory" (DS70202) and Section 4. "Program Memory" (DS70203) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
4.1
Program Address Space
The program address memory space of the dsPIC33FJXXXMCX06/X08/X10 devices is 4M instructions. The space is addressable by a 24-bit value derived from either the 23-bit Program Counter (PC) during program execution, or from table operation or data space remapping as described in Section 4.6 "Interfacing Program and Data Memory Spaces". User access to the program memory space is restricted to the lower half of the address range (0x000000 to 0x7FFFFF). The exception is the use of TBLRD/TBLWT operations, which use TBLPAG<7> to permit access to the Configuration bits and Device ID sections of the configuration memory space. Memory usage for the dsPIC33FJXXXMCX06/X08/X10 family of devices is shown in Figure 4-1.
The dsPIC33FJXXXMCX06/X08/X10 architecture features separate program and data memory spaces and buses. This architecture also allows the direct access of program memory from the data space during code execution.

4.1.1 PROGRAM MEMORY ORGANIZATION 4.1.2 INTERRUPT AND TRAP VECTORS
The program memory space is organized in word-addressable blocks. Although it is treated as 24 bits wide, it is more appropriate to think of each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. The lower word always has an even address, while the upper word has an odd address (Figure 4-2). Program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented by two during code execution. This arrangement also provides compatibility with data memory space addressing and makes it possible to access data in the program memory space. All dsPIC33FJXXXMCX06/X08/X10 devices reserve the addresses between 0x00000 and 0x000200 for hard-coded program execution vectors. A hardware Reset vector is provided to redirect code execution from the default value of the PC on device Reset to the actual start of code. A GOTO instruction is programmed by the user at 0x000000, with the actual address for the start of code at 0x000002. dsPIC33FJXXXMCX06/X08/X10 devices also have two interrupt vector tables located from 0x000004 to 0x0000FF and 0x000100 to 0x0001FF. These vector tables allow each of the many device interrupt sources to be handled by separate Interrupt Service Routines (ISRs). A more detailed discussion of the interrupt vector tables is provided in Section 7.1 "Interrupt Vector Table".

4.2 Data Address Space
The dsPIC33FJXXXMCX06/X08/X10 CPU has a separate 16-bit wide data memory space. The data space is accessed using separate Address Generation Units (AGUs) for read and write operations. Data memory maps of devices with different RAM sizes are shown in Figure 4-3 through Figure 4-5. All Effective Addresses (EAs) in the data memory space are 16 bits wide and point to bytes within the data space. This arrangement gives a data space address range of 64 Kbytes or 32K words. The lower half of the data memory space (that is, when EA<15> = 0) is used for implemented memory addresses, while the upper half (EA<15> = 1) is reserved for the Program Space Visibility area (see Section 4.6.3 "Reading Data from Program Memory Using Program Space Visibility"). dsPIC33FJXXXMCX06/X08/X10 devices implement a total of up to 30 Kbytes of data memory. Should an EA point to a location outside of this area, an all-zero word or byte will be returned. All word accesses must be aligned to an even address. Misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations or translating from 8-bit MCU code. If a misaligned read or write is attempted, an address error trap is generated. If the error occurred on a read, the instruction underway is completed; if it occurred on a write, the instruction will be executed but the write does not occur. In either case, a trap is then executed, allowing the system and/or user to examine the machine state prior to execution of the address Fault. All byte loads into any W register are loaded into the Least Significant Byte. The Most Significant Byte is not modified. A sign-extend instruction (SE) is provided to allow users to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, users can clear the MSb of any W register by executing a zero-extend (ZE) instruction on the appropriate address.
4.2.1
DATA SPACE WIDTH
4.2.3
SFR SPACE
The data memory space is organized in byte addressable, 16-bit wide blocks. Data is aligned in data memory and registers as 16-bit words, but all data space EAs resolve to bytes. The Least Significant Bytes of each word have even addresses, while the Most Significant Bytes have odd addresses.
The first 2 Kbytes of the Near Data Space, from 0x0000 to 0x07FF, is primarily occupied by Special Function Registers (SFRs). These are used by the dsPIC33FJXXXMCX06/X08/X10 core and peripheral modules for controlling the operation of the device. SFRs are distributed among the modules that they control and are generally grouped together by module. Much of the SFR space contains unused addresses; these are read as `0'. Note: The actual set of peripheral features and interrupts varies by the device. Please refer to the corresponding device tables and pinout diagrams for device-specific information.
4.2.2
DATA MEMORY ORGANIZATION AND ALIGNMENT
To maintain backward compatibility with PIC(R) microcontrollers and improve data space memory usage efficiency, the dsPIC33FJXXXMCX06/X08/X10 instruction set supports both word and byte operations. As a consequence of byte accessibility, all effective address calculations are internally scaled to step through word-aligned memory. For example, the core recognizes that Post-Modified Register Indirect Addressing mode [Ws++] will result in a value of Ws + 1 for byte operations and Ws + 2 for word operations. Data byte reads will read the complete word that contains the byte, using the LSb of any EA to determine which byte to select. The selected byte is placed onto the LSb of the data path. That is, data memory and registers are organized as two parallel byte-wide entities with shared (word) address decode but separate write lines. Data byte writes only write to the corresponding side of the array or register which matches the byte address.
4.2.4
NEAR DATA SPACE
The 8-Kbyte area between 0x0000 and 0x1FFF is referred to as the Near Data Space. Locations in this space are directly addressable via a 13-bit absolute address field within all memory direct instructions. Additionally, the whole data space is addressable using MOV instructions, which support Memory Direct Addressing mode with a 16-bit address field, or by using Indirect Addressing mode using a working register as an Address Pointer.

4.2.5 X AND Y DATA SPACES 4.2.6 DMA RAM
The core has two data spaces, X and Y. These data spaces can be considered either separate (for some DSP instructions) or as one unified linear address range (for MCU instructions). The data spaces are accessed using two Address Generation Units (AGUs) and separate data paths. This feature allows certain instructions to concurrently fetch two words from RAM, thereby enabling efficient execution of DSP algorithms such as Finite Impulse Response (FIR) filtering and Fast Fourier Transform (FFT). The X data space is used by all instructions and supports all addressing modes. There are separate read and write data buses for X data space. The X read data bus is the read data path for all instructions that view data space as combined X and Y address space. It is also the X data prefetch path for the dual operand DSP instructions (MAC class). The Y data space is used in concert with the X data space by the MAC class of instructions (CLR, ED, EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide two concurrent data read paths. Both the X and Y data spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X data space. All data memory writes, including in DSP instructions, view data space as combined X and Y address space. The boundary between the X and Y data spaces is device-dependent and is not user-programmable. All effective addresses are 16 bits wide and point to bytes within the data space. Therefore, the data space address range is 64 Kbytes, or 32K words, though the implemented memory locations vary by device. Every dsPIC33FJXXXMCX06/X08/X10 device contains 2 Kbytes of dual ported DMA RAM located at the end of Y data space. Memory locations is part of Y data RAM and is in the DMA RAM space are accessible simultaneously by the CPU and the DMA controller module. DMA RAM is utilized by the DMA controller to store data to be transferred to various peripherals using DMA, as well as data transferred from various peripherals using DMA. The DMA RAM can be accessed by the DMA controller without having to steal cycles from the CPU. When the CPU and the DMA controller attempt to concurrently write to the same DMA RAM location, the hardware ensures that the CPU is given precedence in accessing the DMA RAM location. Therefore, the DMA RAM provides a reliable means of transferring DMA data without ever having to stall the CPU.

4.2.7 SOFTWARE STACK 4.2.8 DATA RAM PROTECTION FEATURE
In addition to its use as a working register, the W15 register in the dsPIC33FJXXXMCX06/X08/X10 devices is also used as a software Stack Pointer. The Stack Pointer always points to the first available free word and grows from lower to higher addresses. It pre-decrements for stack pops and post-increments for stack pushes, as shown in Figure 4-6. For a PC push during any CALL instruction, the MSb of the PC is zero-extended before the push, ensuring that the MSb is always clear. Note: A PC push during exception processing concatenates the SRL register to the MSb of the PC prior to the push. The dsPIC33FJXXXMCX06/X08/X10 devices supports Data RAM protection features which enable segments of RAM to be protected when used in conjunction with Boot and Secure Code Segment Security. BSRAM (Secure RAM segment for BS) is accessible only from the Boot Segment Flash code when enabled. SSRAM (Secure RAM segment for RAM) is accessible only from the Secure Segment Flash code when enabled. See Table 4-1 for an overview of the BSRAM and SSRAM SFRs.
4.3
Instruction Addressing Modes
The Stack Pointer Limit register (SPLIM) associated with the Stack Pointer sets an upper address boundary for the stack. SPLIM is uninitialized at Reset. As is the case for the Stack Pointer, SPLIM<0> is forced to `0' because all stack operations must be word-aligned. Whenever an EA is generated using W15 as a source or destination pointer, the resulting address is compared with the value in SPLIM. If the contents of the Stack Pointer (W15) and the SPLIM register are equal and a push operation is performed, a stack error trap will not occur. The stack error trap will occur on a subsequent push operation. Thus, for example, if it is desirable to cause a stack error trap when the stack grows beyond address 0x2000 in RAM, initialize the SPLIM with the value 0x1FFE. Similarly, a Stack Pointer underflow (stack error) trap is generated when the Stack Pointer address is found to be less than 0x0800. This prevents the stack from interfering with the Special Function Register (SFR) space. A write to the SPLIM register should not be immediately followed by an indirect read operation using W15.
The addressing modes in Table 4-36 form the basis of the addressing modes optimized to support the specific features of individual instructions. The addressing modes provided in the MAC class of instructions are somewhat different from those in the other instruction types.
4.3.1
FILE REGISTER INSTRUCTIONS
Most file register instructions use a 13-bit address field (f) to directly address data present in the first 8192 bytes of data memory (Near Data Space). Most file register instructions employ a working register, W0, which is denoted as WREG in these instructions. The destination is typically either the same file register or WREG (with the exception of the MUL instruction), which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can access the entire data space.
4.3.2
MCU INSTRUCTIONS
The 3-operand MCU instructions are of the following form: Operand 3 = Operand 1 Operand 2 where Operand 1 is always a working register (i.e., the addressing mode can only be register direct) which is referred to as Wb. Operand 2 can be a W register fetched from data memory or a 5-bit literal. The result location can be either a W register or a data memory location. The following addressing modes are supported by MCU instructions: * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified 5-bit or 10-bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes.

TABLE 4-36: FUNDAMENTAL ADDRESSING MODES SUPPORTED
Description The address of the file register is specified explicitly. The contents of a register are accessed directly. The contents of Wn forms the EA. The contents of Wn forms the EA. Wn is post-modified (incremented or decremented) by a constant value. Wn is pre-modified (incremented or decremented) by a signed constant value to form the EA. The sum of Wn and a literal forms the EA. The 2-source operand prefetch registers must be members of the set {W8, W9, W10, W11}. For data reads, W8 and W9 are always directed to the X RAGU and W10 and W11 will always be directed to the Y AGU. The effective addresses generated (before and after modification) must, therefore, be valid addresses within X data space for W8 and W9 and Y data space for W10 and W11. Note: Register Indirect with Register Offset Addressing mode is only available for W9 (in X space) and W11 (in Y space). Addressing Mode File Register Direct Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified
Register Indirect with Register Offset The sum of Wn and Wb forms the EA. Register Indirect with Literal Offset
4.3.3
MOVE AND ACCUMULATOR INSTRUCTIONS
Move instructions and the DSP accumulator class of instructions provide a greater degree of addressing flexibility than other instructions. In addition to the Addressing modes supported by most MCU instructions, move and accumulator instructions also support Register Indirect with Register Offset Addressing mode, also referred to as Register Indexed mode. Note: For the MOV instructions, the Addressing mode specified in the instruction can differ for the source and destination EA. However, the 4-bit Wb (Register Offset) field is shared between both source and destination (but typically only used by one).
In summary, the following addressing modes are supported by the MAC class of instructions: * * * * * Register Indirect Register Indirect Post-Modified by 2 Register Indirect Post-Modified by 4 Register Indirect Post-Modified by 6 Register Indirect with Register Offset (Indexed)
In summary, the following Addressing modes are supported by move and accumulator instructions: * * * * * * * * Register Direct Register Indirect Register Indirect Post-modified Register Indirect Pre-modified Register Indirect with Register Offset (Indexed) Register Indirect with Literal Offset 8-bit Literal 16-bit Literal Note: Not all instructions support all the Addressing modes given above. Individual instructions may support different subsets of these Addressing modes.
4.3.5
OTHER INSTRUCTIONS
Besides the various addressing modes outlined above, some instructions use literal constants of various sizes. For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI instruction uses a 14-bit unsigned literal field. In some instructions, such as ADD Acc, the source of an operand or result is implied by the opcode itself. Certain operations, such as NOP, do not have any operands.
4.4
Modulo Addressing
4.3.4
MAC INSTRUCTIONS
The dual source operand DSP instructions (CLR, ED, EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred to as MAC instructions, utilize a simplified set of addressing modes to allow the user to effectively manipulate the data pointers through register indirect tables.
Modulo Addressing mode is a method of providing an automated means to support circular data buffers using hardware. The objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many DSP algorithms. Modulo Addressing can operate in either data or program space (since the data pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into program space) and Y data spaces. Modulo Addressing
DS70287C-page 64

dsPIC33FJXXXMCX06/X08/X10
can operate on any W register pointer. However, it is not advisable to use W14 or W15 for Modulo Addressing, since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. In general, any particular circular buffer can only be configured to operate in one direction, as there are certain restrictions on the buffer start address (for incrementing buffers) or end address (for decrementing buffers), based upon the direction of the buffer. The only exception to the usage restrictions is for buffers which have a power-of-2 length. As these buffers satisfy the start and end address criteria, they may operate in a bidirectional mode (i.e., address boundary checks will be performed on both the lower and upper address boundaries). The length of a circular buffer is not directly specified. It is determined by the difference between the corresponding start and end addresses. The maximum possible length of the circular buffer is 32K words (64 Kbytes).
4.4.2
W ADDRESS REGISTER SELECTION
The Modulo and Bit-Reversed Addressing Control register, MODCON<15:0>, contains enable flags as well as a W register field to specify the W Address registers. The XWM and YWM fields select which registers will operate with Modulo Addressing. If XWM = 15, X RAGU and X WAGU Modulo Addressing is disabled. Similarly, if YWM = 15, Y AGU Modulo Addressing is disabled. The X Address Space Pointer W register (XWM) to which Modulo Addressing is to be applied is stored in MODCON<3:0> (see Table 4-1). Modulo Addressing is enabled for X data space when XWM is set to any value other than `15' and the XMODEN bit is set at MODCON<15>. The Y Address Space Pointer W register (YWM) to which Modulo Addressing is to be applied is stored in MODCON<7:4>. Modulo Addressing is enabled for Y data space when YWM is set to any value other than `15' and the YMODEN bit is set at MODCON<14>.
4.4.1
START AND END ADDRESS
The Modulo Addressing scheme requires that a starting and ending address be specified and loaded into the 16-bit Modulo Buffer Address registers: XMODSRT, XMODEND, YMODSRT and YMODEND (see Table 4-1). Note: Y space Modulo Addressing EA calculations assume word sized data (LSb of every EA is always clear).

4.4.3 MODULO ADDRESSING APPLICABILITY
Modulo Addressing can be applied to the Effective Address (EA) calculation associated with any W register. It is important to realize that the address boundaries check for addresses less than or greater than the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). Address changes may, therefore, jump beyond boundaries and still be adjusted correctly. Note: The modulo corrected effective address is written back to the register only when Pre-Modify or Post-Modify Addressing mode is used to compute the effective address. When an address offset (e.g., [W7+W2]) is used, Modulo Address correction is performed but the contents of the register remain unchanged. If the length of a bit-reversed buffer is M = 2N bytes, the last `N' bits of the data buffer start address must be zeros. XB<14:0> is the Bit-Reversed Address modifier, or `pivot point', which is typically a constant. In the case of an FFT computation, its value is equal to half of the FFT data buffer size. Note: All bit-reversed EA calculations assume word sized data (LSb of every EA is always clear). The XB value is scaled accordingly to generate compatible (byte) addresses.
4.5
Bit-Reversed Addressing
Bit-Reversed Addressing mode is intended to simplify data reordering for radix-2 FFT algorithms. It is supported by the X AGU for data writes only. The modifier, which may be a constant value or register contents, is regarded as having its bit order reversed. The address source and destination are kept in normal order. Thus, the only operand requiring reversal is the modifier.
When enabled, Bit-Reversed Addressing is only executed for Register Indirect with Pre-Increment or Post-Increment Addressing and word sized data writes. It will not function for any other addressing mode or for byte sized data; normal addresses are generated instead. When Bit-Reversed Addressing is active, the W Address Pointer is always added to the address modifier (XB) and the offset associated with the Register Indirect Addressing mode is ignored. In addition, as word sized data is a requirement, the LSb of the EA is ignored (and always clear). Note: Modulo Addressing and Bit-Reversed Addressing should not be enabled together. In the event that the user attempts to do so, Bit-Reversed Addressing will assume priority for the X WAGU, and X WAGU Modulo Addressing will be disabled. However, Modulo Addressing will continue to function in the X RAGU.
4.5.1
BIT-REVERSED ADDRESSING IMPLEMENTATION
Bit-Reversed Addressing mode is enabled when the following conditions exist: 1. The BWM bits (W register selection) in the MODCON register are any value other than `15' (the stack cannot be accessed using Bit-Reversed Addressing). The BREN bit is set in the XBREV register. The addressing mode used is Register Indirect with Pre-Increment or Post-Increment.
If Bit-Reversed Addressing has already been enabled by setting the BREN (XBREV<15>) bit, then a write to the XBREV register should not be immediately followed by an indirect read operation using the W register that has been designated as the bit-reversed pointer.

4.6 Interfacing Program and Data Memory Spaces
4.6.1 ADDRESSING PROGRAM SPACE
Since the address ranges for the data and program spaces are 16 and 24 bits, respectively, a method is needed to create a 23-bit or 24-bit program address from 16-bit data registers. The solution depends on the interface method to be used. For table operations, the 8-bit Table Page register (TBLPAG) is used to define a 32K word region within the program space. This is concatenated with a 16-bit EA to arrive at a full 24-bit program space address. In this format, the Most Significant bit of TBLPAG is used to determine if the operation occurs in the user memory (TBLPAG<7> = 0) or the configuration memory (TBLPAG<7> = 1). For remapping operations, the 8-bit Program Space Visibility register (PSVPAG) is used to define a 16K word page in the program space. When the Most Significant bit of the EA is `1', PSVPAG is concatenated with the lower 15 bits of the EA to form a 23-bit program space address. Unlike table operations, this limits remapping operations strictly to the user memory area. Table 4-38 and Figure 4-9 show how the program EA is created for table operations and remapping accesses from the data EA. Here, P<23:0> refers to a program space word, whereas D<15:0> refers to a data space word.
The dsPIC33FJXXXMCX06/X08/X10 architecture uses a 24-bit wide program space and a 16-bit wide data space. The architecture is also a modified Harvard scheme, meaning that data can also be present in the program space. To use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. Aside from normal execution, the dsPIC33FJXXXMCX06/X08/X10 architecture provides two methods by which program space can be accessed during operation: * Using table instructions to access individual bytes or words anywhere in the program space * Remapping a portion of the program space into the data space (Program Space Visibility) Table instructions allow an application to read or write to small areas of the program memory. This capability makes the method ideal for accessing data tables that need to be updated from time to time. It also allows access to all bytes of the program word. The remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look ups from a large table of static data. It can only access the least significant word of the program word.

4.6.2 DATA ACCESS FROM PROGRAM MEMORY USING TABLE INSTRUCTIONS
2. TBLRDH (Table Read High): In Word mode, it maps the entire upper word of a program address (P<23:16>) to a data address. Note that D<15:8>, the `phantom' byte, will always be `0'. In Byte mode, it maps the upper or lower byte of the program word to D<7:0> of the data address, as above. Note that the data will always be `0' when the upper `phantom' byte is selected (Byte Select = 1). In a similar fashion, two table instructions, TBLWTH and TBLWTL, are used to write individual bytes or words to a program space address. The details of their operation are explained in Section 5.0 "Flash Program Memory". For all table operations, the area of program memory space to be accessed is determined by the Table Page register (TBLPAG). TBLPAG covers the entire program memory space of the device, including user and configuration spaces. When TBLPAG<7> = 0, the table page is located in the user memory space. When TBLPAG<7> = 1, the page is located in configuration space.
The TBLRDL and TBLWTL instructions offer a direct method of reading or writing the lower word of any address within the program space without going through data space. The TBLRDH and TBLWTH instructions are the only method to read or write the upper 8 bits of a program space word as data. The PC is incremented by two for each successive 24-bit program word. This allows program memory addresses to directly map to data space addresses. Program memory can thus be regarded as two 16-bit word wide address spaces residing side by side, each with the same address range. TBLRDL and TBLWTL access the space which contains the least significant data word, and TBLRDH and TBLWTH access the space which contains the upper data byte. Two table instructions are provided to move byte or word sized (16-bit) data to and from program space. Both function as either byte or word operations. 1. TBLRDL (Table Read Low): In Word mode, it maps the lower word of the program space location (P<15:0>) to a data address (D<15:0>). In Byte mode, either the upper or lower byte of the lower program word is mapped to the lower byte of a data address. The upper byte is selected when Byte Select is `1'; the lower byte is selected when it is `0'.

4.6.3 READING DATA FROM PROGRAM MEMORY USING PROGRAM SPACE VISIBILITY
24-bit program word are used to contain the data. The upper 8 bits of any program space location used as data should be programmed with `1111 1111' or `0000 0000' to force a NOP. This prevents possible issues should the area of code ever be accidentally executed. Note: PSV access is temporarily disabled during table reads/writes.
The upper 32 Kbytes of data space may optionally be mapped into any 16K word page of the program space. This option provides transparent access of stored constant data from the data space without the need to use special instructions (i.e., TBLRDL/H). Program space access through the data space occurs if the Most Significant bit of the data space EA is `1' and program space visibility is enabled by setting the PSV bit in the Core Control register (CORCON<2>). The location of the program memory space to be mapped into the data space is determined by the Program Space Visibility Page register (PSVPAG). This 8-bit register defines any one of 256 possible pages of 16K words in program space. In effect, PSVPAG functions as the upper 8 bits of the program memory address, with the 15 bits of the EA functioning as the lower bits. Note that by incrementing the PC by 2 for each program memory word, the lower 15 bits of data space addresses directly map to the lower 15 bits in the corresponding program space addresses. Data reads to this area add an additional cycle to the instruction being executed, since two program memory fetches are required. Although each data space address, 8000h and higher, maps directly into a corresponding program memory address (see Figure 4-11), only the lower 16 bits of the
For operations that use PSV and are executed outside a REPEAT loop, the MOV and MOV.D instructions require one instruction cycle in addition to the specified execution time. All other instructions require two instruction cycles in addition to the specified execution time. For operations that use PSV and are executed inside a REPEAT loop, there will be some instances that require two instruction cycles in addition to the specified execution time of the instruction: * Execution in the first iteration * Execution in the last iteration * Execution prior to exiting the loop due to an interrupt * Execution upon re-entering the loop after an interrupt is serviced Any other iteration of the REPEAT loop will allow the instruction accessing data using PSV to execute in a single cycle.

then program the digital signal controller just before shipping the product. This also allows the most recent firmware or a custom firmware to be programmed. RTSP is accomplished using TBLRD (table read) and TBLWT (table write) instructions. With RTSP, the user can write program memory data by blocks (or `rows') of 64 instructions (192 bytes) at a time or by single program memory word; and the user can erase program memory in blocks or `pages' of 512 instructions (1536 bytes) at a time.
5.1
The dsPIC33FJXXXMCX06/X08/X10 devices contain internal Flash program memory for storing and executing application code. The memory is readable, writable and erasable during normal operation over the entire VDD range. Flash memory can be programmed in two ways: 1. 2. In-Circuit Serial ProgrammingTM (ICSPTM) programming capability Run-Time Self-Programming (RTSP)
Table Instructions and Flash Programming
ICSP allows a dsPIC33FJXXXMCX06/X08/X10 device to be serially programmed while in the end application circuit. This is simply done with two lines for programming clock and programming data (one of the alternate programming pin pairs: PGECx/PGEDx), and three other lines for power (VDD), ground (VSS) and Master Clear (MCLR). This allows customers to manufacture boards with unprogrammed devices and
Regardless of the method used, all programming of Flash memory is done with the table read and table write instructions. These allow direct read and write access to the program memory space from the data memory while the device is in normal operating mode. The 24-bit target address in the program memory is formed using bits <7:0> of the TBLPAG register and the Effective Address (EA) from a W register specified in the table instruction, as shown in Figure 5-1. The TBLRDL and TBLWTL instructions are used to read or write to bits <15:0> of program memory. TBLRDL and TBLWTL can access program memory in both Word and Byte modes. The TBLRDH and TBLWTH instructions are used to read or write to bits <23:16> of program memory. TBLRDH and TBLWTH can also access program memory in Word or Byte mode.

5.2 RTSP Operation 5.3 Programming Operations
The dsPIC33FJXXXMCX06/X08/X10 Flash program memory array is organized into rows of 64 instructions or 192 bytes. RTSP allows the user to erase a page of memory at a time, which consists of eight rows (512 instructions), and to program one row or one word at a time. Table 26-12 shows typical erase and programming times. The 8-row erase pages and single-row write rows are edge-aligned, from the beginning of program memory, on boundaries of 1536 bytes and 192 bytes, respectively. The program memory implements holding buffers that can contain 64 instructions of programming data. Prior to the actual programming operation, the write data must be loaded into the buffers in sequential order. The instruction words loaded must always be from a group of 64 boundary. The basic sequence for RTSP programming is to set up a Table Pointer, then do a series of TBLWT instructions to load the buffers. Programming is performed by setting the control bits in the NVMCON register. A total of 64 TBLWTL and TBLWTH instructions are required to load the instructions. All of the table write operations are single-word writes (two instruction cycles), because only the buffers are written. A programming cycle is required for programming each row. A complete programming sequence is necessary for programming or erasing the internal Flash in RTSP mode. The processor stalls (waits) until the programming operation is finished. The programming time depends on the FRC accuracy (see Table 26-19) and the value of the FRC Oscillator Tuning register (see Register 9-4). Use the following formula to calculate the minimum and maximum values for the Row Write Time, Page Erase Time and Word Write Cycle Time parameters (see Table 26-12).
EQUATION 5-1:
PROGRAMMING TIME
T ------------------------------------------------------------------------------------------------------------------------7.37 MHz x ( FRC Accuracy )% x ( FRC Tuning )% For example, if the device is operating at +85C, the FRC accuracy will be 2%. If the TUN<5:0> bits (see Register 9-4) are set to `b111111, the Minimum Row Write Time is: 11064 Cycles T RW = ---------------------------------------------------------------------------------------------- = 1.48ms 7.37 MHz x ( 1 + 0.02 ) x ( 1 - 0.00375 ) and, the Maximum Row Write Time is: 11064 Cycles T RW = --------------------------------------------------------------------------------------------- = 1.54ms 7.37 MHz x ( 1 - 0.02 ) x ( 1 - 0.00375 ) Setting the WR bit (NVMCON<15>) starts the operation, and the WR bit is automatically cleared when the operation is finished.
5.4
Control Registers
There are two SFRs used to read and write the program Flash memory: NVMCON and NVMKEY. The NVMCON register (Register 5-1) controls which blocks are to be erased, which memory type is to be programmed and the start of the programming cycle. NVMKEY is a write-only register that is used for write protection. To start a programming or erase sequence, the user must consecutively write 0x55 and 0xAA to the NVMKEY register. Refer to Section 5.3 "Programming Operations" for further details.

5.4.1 PROGRAMMING ALGORITHM FOR FLASH PROGRAM MEMORY
4. 5. The user can program one row of program Flash memory at a time. To do this, it is necessary to erase the 8-row erase page that contains the desired row. The general process is as follows: 1. 2. 3. Read eight rows of program memory (512 instructions) and store it in data RAM. Update the program data in RAM with the desired new data. Erase the block (see Example 5-1): a) Set the NVMOP bits (NVMCON<3:0>) to `0010' to configure for block erase. Set the ERASE (NVMCON<6>) and WREN (NVMCON<14>) bits. b) Write the starting address of the page to be erased into the TBLPAG and W registers. c) Write 0x55 to NVMKEY. d) Write 0xAA to NVMKEY. e) Set the WR bit (NVMCON<15>). The erase cycle begins and the CPU stalls for the duration of the erase cycle. When the erase is done, the WR bit is cleared automatically. Write the first 64 instructions from data RAM into the program memory buffers (see Example 5-2). Write the program block to Flash memory: a) Set the NVMOP bits to `0001' to configure for row programming. Clear the ERASE bit and set the WREN bit. b) Write 0x55 to NVMKEY. c) Write 0xAA to NVMKEY. d) Set the WR bit. The programming cycle begins and the CPU stalls for the duration of the write cycle. When the write to Flash memory is done, the WR bit is cleared automatically. Repeat steps 4 and 5 using the next available 64 instructions from the block in data RAM by incrementing the value in TBLPAG until all 512 instructions are written back to Flash memory.
6.
For protection against accidental operations, the write initiate sequence for NVMKEY must be used to allow any erase or program operation to proceed. After the programming command has been executed, the user must wait for the programming time until programming is complete. The two instructions following the start of the programming sequence should be NOPs, as shown in Example 5-3.

RESET
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 8. "Reset" (DS70192) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
Any active source of Reset will make the SYSRST signal active. Many registers associated with the CPU and peripherals are forced to a known Reset state. Most registers are unaffected by a Reset; their status is unknown on POR and unchanged by all other Resets. Note: Refer to the specific peripheral or CPU section of this manual for register Reset states.
The Reset module combines all Reset sources and controls the device Master Reset Signal, SYSRST. The following is a list of device Reset sources: * * * * * * * POR: Power-on Reset BOR: Brown-out Reset MCLR: Master Clear Pin Reset SWR: RESET Instruction WDT: Watchdog Timer Reset TRAPR: Trap Conflict Reset IOPUWR: Illegal Opcode and Uninitialized W Register Reset
All types of device Reset will set a corresponding status bit in the RCON register to indicate the type of Reset (see Register 6-1). A POR will clear all bits except for the POR bit (RCON<0>), which is set. The user can set or clear any bit at any time during code execution. The RCON bits only serve as status bits. Setting a particular Reset status bit in software does not cause a device Reset to occur. The RCON register also has other bits associated with the Watchdog Timer and device power-saving states. The function of these bits is discussed in other sections of this manual. Note: The status bits in the RCON register should be cleared after they are read so that the next RCON register value after a device Reset will be meaningful.
A simplified block diagram of the Reset module is shown in Figure 6-1.

Clock Source Selection at Reset
6.2
Device Reset Times
If clock switching is enabled, the system clock source at device Reset is chosen, as shown in Table 6-2. If clock switching is disabled, the system clock source is always selected according to the oscillator Configuration bits. Refer to Section 9.0 "Oscillator Configuration" for further details.
The Reset times for various types of device Reset are summarized in Table 6-3. The system Reset signal, SYSRST, is released after the POR and PWRT delay times expire. The time at which the device actually begins to execute code also depends on the system oscillator delays, which include the Oscillator Start-up Timer (OST) and the PLL lock time. The OST and PLL lock times occur in parallel with the applicable SYSRST delay times. The FSCM delay determines the time at which the FSCM begins to monitor the system clock source after the SYSRST signal is released.

TPOR = Power-on Reset delay (10 s nominal). TSTARTUP = Conditional POR delay of 20 s nominal (if on-chip regulator is enabled) or 64 ms nominal Power-up Timer delay (if regulator is disabled). TSTARTUP is also applied to all returns from powered-down states, including waking from Sleep mode, if the regulator is enabled. TRST = Internal state Reset time (20 s nominal). TOST = Oscillator Start-up Timer. A 10-bit counter counts 1024 oscillator periods before releasing the oscillator clock to the system. TLOCK = PLL lock time (20 s nominal). TFSCM = Fail-Safe Clock Monitor delay (100 s nominal).
6.2.1
POR AND LONG OSCILLATOR START-UP TIMES
6.2.2
FAIL-SAFE CLOCK MONITOR (FSCM) AND DEVICE RESETS
The oscillator start-up circuitry and its associated delay timers are not linked to the device Reset delays that occur at power-up. Some crystal circuits (especially low-frequency crystals) have a relatively long start-up time. Therefore, one or more of the following conditions is possible after SYSRST is released: * The oscillator circuit has not begun to oscillate. * The Oscillator Start-up Timer has not expired (if a crystal oscillator is used). * The PLL has not achieved a lock (if PLL is used). The device will not begin to execute code until a valid clock source has been released to the system. Therefore, the oscillator and PLL start-up delays must be considered when the Reset delay time must be known.
If the FSCM is enabled, it begins to monitor the system clock source when SYSRST is released. If a valid clock source is not available at this time, the device automatically switches to the FRC oscillator and the user can switch to the desired crystal oscillator in the Trap Service Routine.
6.2.2.1
FSCM Delay for Crystal and PLL Clock Sources
When the system clock source is provided by a crystal oscillator and/or the PLL, a small delay, TFSCM, is automatically inserted after the POR and PWRT delay times. The FSCM does not begin to monitor the system clock source until this delay expires. The FSCM delay time is nominally 500 s and provides additional time for the oscillator and/or PLL to stabilize. In most cases, the FSCM delay prevents an oscillator failure trap at a device Reset when the PWRT is disabled.

6.3 Special Function Register Reset States
Most of the Special Function Registers (SFRs) associated with the CPU and peripherals are reset to a particular value at a device Reset. The SFRs are grouped by their peripheral or CPU function, and their Reset values are specified in each section of this manual. The Reset value for each SFR does not depend on the type of Reset, with the exception of two registers. The Reset value for the Reset Control register, RCON, depends on the type of device Reset. The Reset value for the Oscillator Control register, OSCCON, depends on the type of Reset and the programmed values of the oscillator Configuration bits in the FOSC Configuration register.

INTERRUPT CONTROLLER
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 6. "Interrupts" (DS70184) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
7.1.1
ALTERNATE INTERRUPT VECTOR TABLE
The Alternate Interrupt Vector Table (AIVT) is located after the IVT, as shown in Figure 7-1. Access to the AIVT is provided by the ALTIVT control bit (INTCON2<15>). If the ALTIVT bit is set, all interrupt and exception processes use the alternate vectors instead of the default vectors. The alternate vectors are organized in the same manner as the default vectors. The AIVT supports debugging by providing a means to switch between an application and a support environment without requiring the interrupt vectors to be reprogrammed. This feature also enables switching between applications for evaluation of different software algorithms at run time. If the AIVT is not needed, the AIVT should be programmed with the same addresses used in the IVT.
The interrupt controller for the dsPIC33FJXXXMCX06/ X08/X10 family of devices reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the dsPIC33FJXXXMCX06/X08/X10 CPU. It has the following features: * Up to eight processor exceptions and software traps * Seven user-selectable priority levels * Interrupt Vector Table (IVT) with up to 118 vectors * A unique vector for each interrupt or exception source * Fixed priority within a specified user priority level * Alternate Interrupt Vector Table (AIVT) for debug support * Fixed interrupt entry and return latencies
7.2
Reset Sequence
A device Reset is not a true exception because the interrupt controller is not involved in the Reset process. The dsPIC33FJXXXMCX06/X08/X10 device clears its registers in response to a Reset, which forces the PC to zero. The digital signal controller then begins program execution at location 0x000000. The user programs a GOTO instruction at the Reset address, which redirects program execution to the appropriate start-up routine. Note: Any unimplemented or unused vector locations in the IVT and AIVT should be programmed with the address of a default interrupt handler routine that contains a RESET instruction.
7.1
Interrupt Vector Table
The Interrupt Vector Table (IVT) is shown in Figure 7-1. The IVT resides in program memory, starting at location 000004h. The IVT contains 126 vectors consisting of eight nonmaskable trap vectors plus up to 118 sources of interrupt. In general, each interrupt source has its own vector. Each interrupt vector contains a 24-bit wide address. The value programmed into each interrupt vector location is the starting address of the associated Interrupt Service Routine (ISR). Interrupt vectors are prioritized in terms of their natural priority; this priority is linked to their position in the vector table. All other things being equal, lower addresses have a higher natural priority. For example, the interrupt associated with vector 0 will take priority over interrupts at any other vector address. The dsPIC33FJXXXMCX06/X08/X10 family of devices implement up to 67 unique interrupts and five nonmaskable traps. These are summarized in Table 7-1 and Table 7-2.

7.3 Interrupt Control and Status Registers
The IPC registers are used to set the interrupt priority level for each source of interrupt. Each user interrupt source can be assigned to one of eight priority levels. The INTTREG register contains the associated interrupt vector number and the new CPU interrupt priority level, which are latched into vector number (VECNUM<6:0>) and Interrupt level (ILR<3:0>) bit fields in the INTTREG register. The new interrupt priority level is the priority of the pending interrupt. The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence that they are listed in Table 7-1. For example, the INT0 (External Interrupt 0) is shown as having vector number 8 and a natural order priority of 0. Thus, the INT0IF bit is found in IFS0<0>, the INT0IE bit in IEC0<0> and the INT0IP bits in the first position of IPC0 (IPC0<2:0>). Although they are not specifically part of the interrupt control hardware, two of the CPU Control registers contain bits that control interrupt functionality. The CPU STATUS register, SR, contains the IPL<2:0> bits (SR<7:5>). These bits indicate the current CPU interrupt priority level. The user can change the current CPU priority level by writing to the IPL bits. The CORCON register contains the IPL3 bit which, together with IPL<2:0>, also indicates the current CPU priority level. IPL3 is a read-only bit so that trap events cannot be masked by the user software. All Interrupt registers are described in Register 7-1 through Register 7-32 in the following pages.
dsPIC33FJXXXMCX06/X08/X10 devices implement a total of 30 registers for the interrupt controller: * * * * * * INTCON1 INTCON2 IFS0 through IFS4 IEC0 through IEC4 IPC0 through IPC17 INTTREG
Global interrupt control functions are controlled from INTCON1 and INTCON2. INTCON1 contains the Interrupt Nesting Disable (NSTDIS) bit as well as the control and status flags for the processor trap sources. The INTCON2 register controls the external interrupt request signal behavior and the use of the Alternate Interrupt Vector Table. The IFS registers maintain all of the interrupt request flags. Each source of interrupt has a Status bit, which is set by the respective peripherals or external signal and is cleared via software. The IEC registers maintain all of the interrupt enable bits. These control bits are used to individually enable interrupts from the peripherals or external signals.

Interrupt Setup Procedures
INITIALIZATION
7.4.3
TRAP SERVICE ROUTINE
To configure an interrupt source, do the following: Set the NSTDIS bit (INTCON1<15>) if nested interrupts are not desired. Select the user-assigned priority level for the interrupt source by writing the control bits in the appropriate IPCx register. The priority level will depend on the specific application and type of interrupt source. If multiple priority levels are not desired, the IPCx register control bits for all enabled interrupt sources may be programmed to the same non-zero value. Note: At a device Reset, the IPCx registers are initialized such that all user interrupt sources are assigned to priority level 4.
A Trap Service Routine (TSR) is coded like an ISR, except that the appropriate trap status flag in the INTCON1 register must be cleared to avoid re-entry into the TSR.
7.4.4
INTERRUPT DISABLE
All user interrupts can be disabled using the following procedure: 1. 2. Push the current SR value onto the software stack using the PUSH instruction. Force the CPU to priority level 7 by inclusive ORing the value OEh with SRL.
To enable user interrupts, the POP instruction may be used to restore the previous SR value. Note that only user interrupts with a priority level of 7 or less can be disabled. Trap sources (level 8-level 15) cannot be disabled. The DISI instruction provides a convenient way to disable interrupts of priority levels 1-6 for a fixed period of time. Level 7 interrupt sources are not disabled by the DISI instruction.
3. 4.
Clear the interrupt flag status bit associated with the peripheral in the associated IFSx register. Enable the interrupt source by setting the interrupt enable control bit associated with the source in the appropriate IECx register.
7.4.2
INTERRUPT SERVICE ROUTINE
The method that is used to declare an ISR and initialize the IVT with the correct vector address will depend on the programming language (i.e., C or assembler) and the language development tool suite that is used to develop the application. In general, the user must clear the interrupt flag in the appropriate IFSx register for the source of interrupt that the ISR handles. Otherwise, the ISR will be re-entered immediately after exiting the routine. If the ISR is coded in assembly language, it must be terminated using a RETFIE instruction to unstack the saved PC value, SRL value and old CPU priority level.

DIRECT MEMORY ACCESS (DMA)
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 22. "Direct Memory Access (DMA)" (DS70182) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
The DMA controller features eight identical data transfer channels. Each channel has its own set of control and status registers. Each DMA channel can be configured to copy data either from buffers stored in dual port DMA RAM to peripheral SFRs or from peripheral SFRs to buffers in DMA RAM. The DMA controller supports the following features: * Word or byte sized data transfers. * Transfers from peripheral to DMA RAM or DMA RAM to peripheral. * Indirect Addressing of DMA RAM locations with or without automatic post-increment. * Peripheral Indirect Addressing - In some peripherals, the DMA RAM read/write addresses may be partially derived from the peripheral. * One-Shot Block Transfers - Terminating DMA transfer after one block transfer. * Continuous Block Transfers - Reloading DMA RAM buffer start address after every block transfer is complete. * Ping-Pong Mode - Switching between two DMA RAM start addresses between successive block transfers, thereby filling two buffers alternately. * Automatic or manual initiation of block transfers. * Each channel can select from 20 possible sources of data sources or destinations. For each DMA channel, a DMA interrupt request is generated when a block transfer is complete. Alternatively, an interrupt can be generated when half of the block has been filled.
Direct Memory Access (DMA) is a very efficient mechanism of copying data between peripheral SFRs (e.g., the UART Receive register and Input Capture 1 buffer) and buffers or variables stored in RAM, with minimal CPU intervention. The DMA controller can automatically copy entire blocks of data without requiring the user software to read or write the peripheral Special Function Registers (SFRs) every time a peripheral interrupt occurs. The DMA controller uses a dedicated bus for data transfers and, therefore, does not steal cycles from the code execution flow of the CPU. To exploit the DMA capability, the corresponding user buffers or variables must be located in DMA RAM. The dsPIC33FJXXXMCX06/X08/X10 peripherals that can utilize DMA are listed in Table 8-1 along with their associated Interrupt Request (IRQ) numbers.

DMAC Registers
Each DMAC Channel x (x = 0, 1, 2, 3, 4, 5, 6 or 7) contains the following registers: * A 16-bit DMA Channel Control register (DMAxCON) * A 16-bit DMA Channel IRQ Select register (DMAxREQ) * A 16-bit DMA RAM Primary Start Address Offset register (DMAxSTA) * A 16-bit DMA RAM Secondary Start Address Offset register (DMAxSTB) * A 16-bit DMA Peripheral Address register (DMAxPAD) * A 10-bit DMA Transfer Count register (DMAxCNT) An additional pair of status registers, DMACS0 and DMACS1, are common to all DMAC channels.

OSCILLATOR CONFIGURATION
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 7. "Oscillator" (DS70186) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
The dsPIC33FJXXXMCX06/X08/X10 oscillator system provides the following: * Various external and internal oscillator options as clock sources
* An on-chip PLL to scale the internal operating frequency to the required system clock frequency * The internal FRC oscillator can also be used with the PLL, thereby allowing full-speed operation without any external clock generation hardware * Clock switching between various clock sources * Programmable clock postscaler for system power savings * A Fail-Safe Clock Monitor (FSCM) that detects clock failure and takes fail-safe measures * A Clock Control register (OSCCON) * Nonvolatile Configuration bits for main oscillator selection A simplified diagram of the oscillator system is shown in Figure 9-1.

9.1 CPU Clocking System
There are seven system clock options provided by the dsPIC33FJXXXMCX06/X08/X10: * * * * * * * FRC Oscillator FRC Oscillator with PLL Primary (XT, HS or EC) Oscillator Primary Oscillator with PLL Secondary (LP) Oscillator LPRC Oscillator FRC Oscillator with postscaler POSCMD<1:0> (FOSC<1:0>), select the oscillator source that is used at a Power-on Reset. The FRC primary oscillator is the default (unprogrammed) selection. The Configuration bits allow users to choose between twelve different clock modes, shown in Table 9-1. The output of the oscillator (or the output of the PLL if a PLL mode has been selected), FOSC, is divided by 2 to generate the device instruction clock (FCY) and the peripheral clock time base (FP). FCY defines the operating speed of the device, and speeds up to 40 MHz are supported by the dsPIC33FJXXXMCX06/ X08/X10 architecture. Instruction execution speed or device operating frequency, FCY, is given by the following equation:
9.1.1
SYSTEM CLOCK SOURCES
The FRC (Fast RC) internal oscillator runs at a nominal frequency of 7.37 MHz. The user software can tune the FRC frequency. User software can optionally specify a factor (ranging from 1:2 to 1:256) by which the FRC clock frequency is divided. This factor is selected using the FRCDIV<2:0> (CLKDIV<10:8>) bits. The primary oscillator can use one of the following as its clock source: 1. XT (Crystal): Crystals and ceramic resonators in the range of 3 MHz to 10 MHz. The crystal is connected to the OSC1 and OSC2 pins. HS (High-Speed Crystal): Crystals in the range of 10 MHz to 40 MHz. The crystal is connected to the OSC1 and OSC2 pins. EC (External Clock): External clock signal is directly applied to the OSC1 pin.

PLL CONFIGURATION
2.
The primary oscillator and internal FRC oscillator can optionally use an on-chip PLL to obtain higher speeds of operation. The PLL provides a significant amount of flexibility in selecting the device operating speed. A block diagram of the PLL is shown in Figure 9-2. The output of the primary oscillator or FRC, denoted as `FIN', is divided down by a prescale factor (N1) of 2, 3, ... or 33 before being provided to the PLL's Voltage Controlled Oscillator (VCO). The input to the VCO must be selected to be in the range of 0.8 MHz to 8 MHz. Since the minimum prescale factor is 2, this implies that FIN must be chosen to be in the range of 1.6 MHz to 16 MHz. The prescale factor, `N1', is selected using the PLLPRE<4:0> bits (CLKDIV<4:0>). The PLL Feedback Divisor, selected using the PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor, `M', by which the input to the VCO is multiplied. This factor must be selected such that the resulting VCO output frequency is in the range of 100 MHz to 200 MHz. The VCO output is further divided by a postscale factor, `N2'. This factor is selected using the PLLPOST<1:0> bits (CLKDIV<7:6>). `N2' can be either 2, 4 or 8, and must be selected such that the PLL output frequency (FOSC) is in the range of 12.5 MHz to 80 MHz, which generates device operating speeds of 6.25-40 MIPS. For a primary oscillator or FRC oscillator output, `FIN', the PLL output, `FOSC', is given by the following equation:
3.
The secondary (LP) oscillator is designed for low power and uses a 32.768 kHz crystal or ceramic resonator. The LP oscillator uses the SOSCI and SOSCO pins. The LPRC (Low-Power RC) internal oscIllator runs at a nominal frequency of 32.768 kHz. It is also used as a reference clock by the Watchdog Timer (WDT) and Fail-Safe Clock Monitor (FSCM). The clock signals generated by the FRC and primary oscillators can be optionally applied to an on-chip Phase Locked Loop (PLL) to provide a wide range of output frequencies for device operation. PLL configuration is described in Section 9.1.3 "PLL Configuration". The FRC frequency depends on the FRC accuracy (see Table 26-19) and the value of the FRC Oscillator Tuning register (see Register 9-4).
9.1.2
SYSTEM CLOCK SELECTION
The oscillator source that is used at a device Power-on Reset event is selected using Configuration bit settings. The oscillator Configuration bit settings are located in the Configuration registers in the program memory. (Refer to Section 23.1 "Configuration Bits" for further details.) The Initial Oscillator Selection Configuration bits, FNOSC<2:0> (FOSCSEL<2:0>), and the Primary Oscillator Mode Select Configuration bits,

For example, suppose a 10 MHz crystal is being used with "XT with PLL" as the selected oscillator mode. If PLLPRE<4:0> = 0, then N1 = 2. This yields a VCO input of 10/2 = 5 MHz, which is within the acceptable range of 0.8-8 MHz. If PLLDIV<8:0> = 0x1E, then M = 32. This yields a VCO output of 5 * 32 = 160 MHz, which is within the 100-200 MHz ranged needed. If PLLPOST<1:0> = 0, then N2 = 2. This provides a Fosc of 160/2 = 80 MHz. The resultant device operating speed is 80/2 = 40 MIPS.

9.2 Clock Switching Operation
2. Applications are free to switch between any of the four clock sources (Primary, LP, FRC and LPRC) under software control at any time. To limit the possible side effects that could result from this flexibility, dsPIC33FJXXXMCX06/X08/X10 devices have a safeguard lock built into the switch process. Note: Primary Oscillator mode has three different submodes (XT, HS and EC) which are determined by the POSCMD<1:0> Configuration bits. While an application can switch to and from Primary Oscillator mode in software, it cannot switch between the different primary submodes without reprogramming the device. If a valid clock switch has been initiated, the LOCK (OSCCON<5>) and the CF (OSCCON<3>) status bits are cleared. The new oscillator is turned on by the hardware if it is not currently running. If a crystal oscillator must be turned on, the hardware waits until the Oscillator Start-up Timer (OST) expires. If the new source is using the PLL, the hardware waits until a PLL lock is detected (LOCK = 1). The hardware waits for 10 clock cycles from the new clock source and then performs the clock switch. The hardware clears the OSWEN bit to indicate a successful clock transition. In addition, the NOSC bit values are transferred to the COSC status bits. The old clock source is turned off at this time, with the exception of LPRC (if WDT or FSCM are enabled) or LP (if LPOSCEN remains set). Note 1: The processor continues to execute code throughout the clock switching sequence. Timing sensitive code should not be executed during this time. 2: Direct clock switches between any primary oscillator mode with PLL and FRCPLL mode are not permitted. This applies to clock switches in either direction. In these instances, the application must switch to FRC mode as a transition clock source between the two PLL modes. 3: Refer to 7. "Oscillator" (DS70186) in the "dsPIC33F Family Reference Manual" for details.

9.2.1
ENABLING CLOCK SWITCHING
To enable clock switching, the FCKSM1 Configuration bit in the Configuration register must be programmed to `0'. (Refer to Section 23.1 "Configuration Bits" for further details.) If the FCKSM1 Configuration bit is unprogrammed (`1'), the clock switching function and Fail-Safe Clock Monitor function are disabled. This is the default setting. The NOSC control bits (OSCCON<10:8>) do not control the clock selection when clock switching is disabled. However, the COSC bits (OSCCON<14:12>) reflect the clock source selected by the FNOSC Configuration bits. The OSWEN control bit (OSCCON<0>) has no effect when clock switching is disabled. It is held at `0' at all times.
9.2.2
OSCILLATOR SWITCHING SEQUENCE
9.3
Fail-Safe Clock Monitor (FSCM)
At a minimum, performing a clock switch requires the following basic sequence: 1. If desired, read the COSC bits (OSCCON<14:12>) to determine the current oscillator source. Perform the unlock sequence to allow a write to the OSCCON register high byte. Write the appropriate value to the NOSC control bits (OSCCON<10:8>) for the new oscillator source. Perform the unlock sequence to allow a write to the OSCCON register low byte. Set the OSWEN bit to initiate the oscillator switch.
2. 3.
The Fail-Safe Clock Monitor (FSCM) allows the device to continue to operate even in the event of an oscillator failure. The FSCM function is enabled by programming. If the FSCM function is enabled, the LPRC internal oscillator runs at all times (except during Sleep mode) and is not subject to control by the Watchdog Timer. In the event of an oscillator failure, the FSCM generates a clock failure trap event and switches the system clock over to the FRC oscillator. Then the application program can either attempt to restart the oscillator or execute a controlled shutdown. The trap can be treated as a warm Reset by simply loading the Reset address into the oscillator fail trap vector. If the PLL multiplier is used to scale the system clock, the internal FRC is also multiplied by the same factor on clock failure. Essentially, the device switches to FRC with PLL on a clock failure.
4. 5.
Once the basic sequence is completed, the system clock hardware responds automatically as follows: 1. The clock switching hardware compares the COSC status bits with the new value of the NOSC control bits. If they are the same, then the clock switch is a redundant operation. In this case, the OSWEN bit is cleared automatically and the clock switch is aborted.

POWER-SAVING FEATURES
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 9. "Watchdog Timer and Power-Saving Modes" (DS70196) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
10.2
Instruction-Based Power-Saving Modes
dsPIC33FJXXXMCX06/X08/X10 devices have two special power-saving modes that are entered through the execution of a special PWRSAV instruction. Sleep mode stops clock operation and halts all code execution. Idle mode halts the CPU and code execution, but allows peripheral modules to continue operation. The assembly syntax of the PWRSAV instruction is shown in Example 10-1. Note: SLEEP_MODE and IDLE_MODE are constants defined in the assembler include file for the selected device.
The dsPIC33FJXXXMCX06/X08/X10 devices provide the ability to manage power consumption by selectively managing clocking to the CPU and the peripherals. In general, a lower clock frequency and a reduction in the number of circuits being clocked constitutes lower consumed power. dsPIC33FJXXXMCX06/X08/X10 devices can manage power consumption in four different ways: * * * * Clock frequency Instruction-based Sleep and Idle modes Software-controlled Doze mode Selective peripheral control in software
Sleep and Idle modes can be exited as a result of an enabled interrupt, WDT time-out or a device Reset. When the device exits these modes, it is said to "wake-up".
10.2.1
SLEEP MODE
Sleep mode has the following features: * The system clock source is shut down. If an on-chip oscillator is used, it is turned off. * The device current consumption is reduced to a minimum, provided that no I/O pin is sourcing current. * The Fail-Safe Clock Monitor does not operate during Sleep mode since the system clock source is disabled. * The LPRC clock continues to run in Sleep mode if the WDT is enabled. * The WDT, if enabled, is automatically cleared prior to entering Sleep mode. * Some device features or peripherals may continue to operate in Sleep mode. This includes items such as the input change notification on the I/O ports and peripherals that use an external clock input. Any peripheral that requires the system clock source for its operation is disabled in Sleep mode. The device will wake-up from Sleep mode on any of the following events: * Any interrupt source that is individually enabled * Any form of device Reset * A WDT time-out On wake-up from Sleep, the processor restarts with the same clock source that was active when Sleep mode was entered.
Combinations of these methods can be used to selectively tailor an application's power consumption while still maintaining critical application features, such as timing-sensitive communications.
10.1
Clock Frequency and Clock Switching
dsPIC33FJXXXMCX06/X08/X10 devices allow a wide range of clock frequencies to be selected under application control. If the system clock configuration is not locked, users can choose low-power or high-precision oscillators by simply changing the NOSC bits (OSCCON<10:8>). The process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in Section 9.0 "Oscillator Configuration".

10.2.2 IDLE MODE
Idle mode has the following features: * The CPU stops executing instructions. * The WDT is automatically cleared. * The system clock source remains active. By default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see Section 10.4 "Peripheral Module Disable"). * If the WDT or FSCM is enabled, the LPRC also remains active. The device will wake from Idle mode on any of the following events: * Any interrupt that is individually enabled * Any device Reset * A WDT time-out On wake-up from Idle, the clock is reapplied to the CPU and instruction execution begins immediately, starting with the instruction following the PWRSAV instruction or the first instruction in the ISR. Doze mode is enabled by setting the DOZEN bit (CLKDIV<11>). The ratio between peripheral and core clock speed is determined by the DOZE<2:0> bits (CLKDIV<14:12>). There are eight possible configurations, from 1:1 to 1:128, with 1:1 being the default setting. It is also possible to use Doze mode to selectively reduce power consumption in event-driven applications. This allows clock-sensitive functions, such as synchronous communications, to continue without interruption while the CPU idles, waiting for something to invoke an interrupt routine. Enabling the automatic return to full-speed CPU operation on interrupts is enabled by setting the ROI bit (CLKDIV<15>). By default, interrupt events have no effect on Doze mode operation. For example, suppose the device is operating at 20 MIPS and the CAN module has been configured for 500 kbps based on this device operating speed. If the device is now placed in Doze mode with a clock frequency ratio of 1:4, the CAN module continues to communicate at the required bit rate of 500 kbps, but the CPU now starts executing instructions at a frequency of 5 MIPS.
10.2.3
INTERRUPTS COINCIDENT WITH POWER SAVE INSTRUCTIONS
10.4
Peripheral Module Disable
Any interrupt that coincides with the execution of a PWRSAV instruction is held off until entry into Sleep or Idle mode has completed. The device then wakes up from Sleep or Idle mode.
10.3
Doze Mode
Generally, changing clock speed and invoking one of the power-saving modes are the preferred strategies for reducing power consumption. There may be circumstances, however, where this is not practical. For example, it may be necessary for an application to maintain uninterrupted synchronous communication, even while it is doing nothing else. Reducing system clock speed may introduce communication errors, while using a power-saving mode may stop communications completely. Doze mode is a simple and effective alternative method to reduce power consumption while the device is still executing code. In this mode, the system clock continues to operate from the same source and at the same speed. Peripheral modules continue to be clocked at the same speed, while the CPU clock speed is reduced. Synchronization between the two clock domains is maintained, allowing the peripherals to access the SFRs while the CPU executes code at a slower rate.
The Peripheral Module Disable (PMD) registers provide a method to disable a peripheral module by stopping all clock sources supplied to that module. When a peripheral is disabled via the appropriate PMD control bit, the peripheral is in a minimum power consumption state. The control and status registers associated with the peripheral are also disabled, so writes to those registers will have no effect and read values will be invalid. A peripheral module is only enabled if both the associated bit in the PMD register is cleared and the peripheral is supported by the specific dsPIC(R) DSC variant. If the peripheral is present in the device, it is enabled in the PMD register by default. Note: If a PMD bit is set, the corresponding module is disabled after a delay of 1 instruction cycle. Similarly, if a PMD bit is cleared, the corresponding module is enabled after a delay of 1 instruction cycle (assuming the module control registers are already configured to enable module operation).

I/O PORTS
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 10. "I/O Ports" (DS70193) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
When a peripheral is enabled and actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. The I/O pin may be read, but the output driver for the parallel port bit will be disabled. If a peripheral is enabled but the peripheral is not actively driving a pin, that pin may be driven by a port. All port pins have three registers directly associated with their operation as digital I/O. The data direction register (TRISx) determines whether the pin is an input or an output. If the data direction bit is a `1', then the pin is an input. All port pins are defined as inputs after a Reset. Reads from the latch (LATx), read the latch. Writes to the latch, write the latch. Reads from the port (PORTx), read the port pins, while writes to the port pins, write the latch. Any bit and its associated data and control registers that are not valid for a particular device will be disabled. That means the corresponding LATx and TRISx registers and the port pins will read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs. An example is the INT4 pin. Note: The voltage on a digital input pin can be between -0.3V to 5.6V.
All of the device pins (except VDD, VSS, MCLR and OSC1/CLKIN) are shared between the peripherals and the parallel I/O ports. All I/O input ports feature Schmitt Trigger inputs for improved noise immunity.
11.1
Parallel I/O (PIO) Ports
A parallel I/O port that shares a pin with a peripheral is, in general, subservient to the peripheral. The peripheral's output buffer data and control signals are provided to a pair of multiplexers. The multiplexers select whether the peripheral or the associated port has ownership of the output data and control signals of the I/O pin. The logic also prevents "loop through," in which a port's digital output can drive the input of a peripheral that shares the same pin. Figure 11-1 shows how ports are shared with other peripherals and the associated I/O pin to which they are connected.

11.2 Open-Drain Configuration 11.4 I/O Port Write/Read Timing
In addition to the PORT, LAT and TRIS registers for data control, some port pins can also be individually configured for either digital or open-drain output. This is controlled by the Open-Drain Control register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs higher than VDD (e.g., 5V) on any desired digital-only pins by using external pull-up resistors. The maximum open-drain voltage allowed is the same as the maximum VIH specification. See "Pin Diagrams" for the available pins and their functionality. One instruction cycle is required between a port direction change or port write operation and a read operation of the same port. Typically, this instruction would be a NOP.
11.5
Input Change Notification
11.3
Configuring Analog Port Pins
The input change notification function of the I/O ports allows the dsPIC33FJXXXMCX06/X08/X10 devices to generate interrupt requests to the processor in response to a change-of-state on selected input pins. This feature is capable of detecting input change-of-states even in Sleep mode, when the clocks are disabled. Depending on the device pin count, there are up to 24 external signals (CN0 through CN23) that can be selected (enabled) for generating an interrupt request on a change-of-state. There are four control registers associated with the CN module. The CNEN1 and CNEN2 registers contain the CN interrupt enable (CNxIE) control bits for each of the CN input pins. Setting any of these bits enables a CN interrupt for the corresponding pins. Each CN pin also has a weak pull-up connected to it. The pull-ups act as a current source that is connected to the pin and eliminate the need for external resistors when push button or keypad devices are connected. The pull-ups are enabled separately using the CNPU1 and CNPU2 registers, which contain the weak pull-up enable (CNxPUE) bits for each of the CN pins. Setting any of the control bits enables the weak pull-ups for the corresponding pins. Note: Pull-ups on change notification pins should always be disabled whenever the port pin is configured as a digital output.
The ADxPCFGH, ADxPCFGL and TRIS registers control the operation of the ADC port pins. The port pins that are desired as analog inputs must have their corresponding TRIS bit set (input). If the TRIS bit is cleared (output), the digital output level (VOH or VOL) is converted. Clearing any bit in the ADxPCFGH or ADxPCFGL register configures the corresponding bit to be an analog pin. This is also the Reset state of any I/O pin that has an analog (ANx) function associated with it. Note: In devices with two ADC modules, if the corresponding PCFG bit in either AD1PCFGH(L) and AD2PCFGH(L) is cleared, the pin is configured as an analog input.
When reading the PORT register, all pins configured as analog input channels will read as cleared (a low level). Pins configured as digital inputs will not convert an analog input. Analog levels on any pin that is defined as a digital input (including the ANx pins) can cause the input buffer to consume current that exceeds the device specifications. Note: The voltage on an analog input pin can be between -0.3V to (VDD + 0.3 V).

TIMER1
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 11. "Timers" (DS70205) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
Timer1 also supports the following features: * Timer gate operation * Selectable prescaler settings * Timer operation during CPU Idle and Sleep modes * Interrupt on 16-bit Period register match or falling edge of external gate signal Figure 12-1 presents a block diagram of the 16-bit timer module. To configure Timer1 for operation, do the following: 1. 2. 3. 4. 5. 6. Set the TON bit (= 1) in the T1CON register. Select the timer prescaler ratio using the TCKPS<1:0> bits in the T1CON register. Set the Clock and Gating modes using the TCS and TGATE bits in the T1CON register. Set or clear the TSYNC bit in T1CON to select synchronous or asynchronous operation. Load the timer period value into the PR1 register. If interrupts are required, set the interrupt enable bit, T1IE. Use the priority bits, T1IP<2:0>, to set the interrupt priority.
The Timer1 module is a 16-bit timer, which can serve as the time counter for the real-time clock or operate as a free-running interval timer/counter. Timer1 can operate in three modes: * 16-bit Timer * 16-bit Synchronous Counter * 16-bit Asynchronous Counter

TIMER2/3, TIMER4/5, TIMER6/7 AND TIMER8/9
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 11. "Timers" (DS70205) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
Note:
For 32-bit operation, T3CON, T5CON, T7CON and T9CON control bits are ignored. Only T2CON, T4CON, T6CON and T8CON control bits are used for setup and control. Timer2, Timer4, Timer6 and Timer8 clock and gate inputs are utilized for the 32-bit timer modules, but an interrupt is generated with the Timer3, Timer5, Ttimer7 and Timer9 interrupt flags.
To configure Timer2/3, Timer4/5, Timer6/7 or Timer8/9 for 32-bit operation, do the following: 1. 2. 3. 4. Set the corresponding T32 control bit. Select the prescaler ratio for Timer2, Timer4, Timer6 or Timer8 using the TCKPS<1:0> bits. Set the Clock and Gating modes using the corresponding TCS and TGATE bits. Load the timer period value. PR3, PR5, PR7 or PR9 contains the most significant word of the value, while PR2, PR4, PR6 or PR8 contains the least significant word. If interrupts are required, set the interrupt enable bit, T3IE, T5IE, T7IE or T9IE. Use the priority bits, T3IP<2:0>, T5IP<2:0>, T7IP<2:0> or T9IP<2:0>, to set the interrupt priority. While Timer2, Timer4, Timer6 or Timer8 control the timer, the interrupt appears as a Timer3, Timer5, Timer7 or Timer9 interrupt. Set the corresponding TON bit.
The Timer2/3, Timer4/5, Timer6/7 and Timer8/9 modules are 32-bit timers that can also be configured as four independent 16-bit timers with selectable operating modes. As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and Timer8/9 operate in three modes: * Two Independent 16-bit Timers (e.g., Timer2 and Timer3) with all 16-bit operating modes (except Asynchronous Counter mode) * Single 32-bit Timer * Single 32-bit Synchronous Counter They also support the following features: Timer Gate Operation Selectable Prescaler Settings Timer Operation during Idle and Sleep modes Interrupt on a 32-bit Period Register Match Time Base for Input Capture and Output Compare Modules (Timer2 and Timer3 only) * ADC1 Event Trigger (Timer2/3 only) * ADC2 Event Trigger (Timer4/5 only) Individually, all eight of the 16-bit timers can function as synchronous timers or counters. They also offer the features listed above, except for the event trigger; this is implemented only with Timer2/3. The operating modes and enabled features are determined by setting the appropriate bit(s) in the T2CON, T3CON, T4CON, T5CON, T6CON, T7CON, T8CON and T9CON registers. T2CON, T4CON, T6CON and T8CON are shown in generic form in Register 13-1. T3CON, T5CON, T7CON and T9CON are shown in Register 13-2. For 32-bit timer/counter operation, Timer2, Timer4, Timer6 or Timer8 is the least significant word; Timer3, Timer5, Timer7 or Timer9 is the most significant word of the 32-bit timers. * * * * *
5.
6.
The timer value at any point is stored in the register pair, TMR3:TMR2, TMR5:TMR4, TMR7:TMR6 or TMR9:TMR8. TMR3, TMR5, TMR7 or TMR9 always contain the most significant word of the count, while TMR2, TMR4, TMR6 or TMR8 contain the least significant word. To configure any of the timers for individual 16-bit operation, do the following: 1. 2. 3. 4. 5. Clear the T32 bit corresponding to that timer. Select the timer prescaler ratio using the TCKPS<1:0> bits. Set the Clock and Gating modes using the TCS and TGATE bits. Load the timer period value into the PRx register. If interrupts are required, set the interrupt enable bit, TxIE. Use the priority bits, TxIP<2:0>, to set the interrupt priority. Set the TON bit.
6.
A block diagram for a 32-bit timer pair (Timer4/5) example is shown in Figure 13-1, and a timer (Timer4) operating in 16-bit mode example is shown in Figure 13-2. Note: Only Timer2 and Timer3 can trigger a DMA data transfer.

Capture timer value on every edge (rising and falling) of input at ICx pin Prescaler Capture Event modes -Capture timer value on every 4th rising edge of input at ICx pin -Capture timer value on every 16th rising edge of input at ICx pin
Each input capture channel can select between one of two 16-bit timers (Timer2 or Timer3) for the time base. The selected timer can use either an internal or external clock. Other operational features include the following: * Device wake-up from capture pin during CPU Sleep and Idle modes * Interrupt on input capture event * 4-word FIFO buffer for capture values - Interrupt optionally generated after 1, 2, 3 or 4 buffer locations are filled * Input capture can also be used to provide additional sources of external interrupts Note: Only IC1 and IC2 can trigger a DMA data transfer. If DMA data transfers are required, the FIFO buffer size must be set to `1' (ICI<1:0> = 00).
The input capture module is useful in applications requiring frequency (period) and pulse measurement. The dsPIC33FJXXXMCX06/X08/X10 devices support up to eight input capture channels. The input capture module captures the 16-bit value of the selected Time Base register when an event occurs at the ICx pin. The events that cause a capture event are listed below in three categories: 1. Simple Capture Event modes -Capture timer value on every falling edge of input at ICx pin -Capture timer value on every rising edge of input at ICx pin

OUTPUT COMPARE
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "dsPIC33F Family Reference Manual", Section 13. "Output Compare" (DS70209), which is available on the Microchip web site (www.microchip.com).
The state of the output pin changes when the timer value matches the Compare register value. The output compare module generates either a single output pulse, or a sequence of output pulses, by changing the state of the output pin on the compare match events. The output compare module can also generate interrupts on compare match events. The output compare module has multiple operating modes: * * * * * * * Active-Low One-Shot mode Active-High One-Shot mode Toggle mode Delayed One-Shot mode Continuous Pulse mode PWM mode without Fault Protection PWM mode with Fault Protection
The output compare module can select either Timer2 or Timer3 for its time base. The module compares the value of the timer with the value of one or two Compare registers depending on the operating mode selected.

15.1 Output Compare Modes
Configure the Output Compare modes by setting the appropriate Output Compare Mode (OCM<2:0>) bits in the Output Compare Control (OCxCON<2:0>) register. Table 15-1 lists the different bit settings for the Output Compare modes. Figure 15-2 illustrates the output compare operation for various modes. The user application must disable the associated timer when writing to the Output Compare Control registers to avoid malfunctions. Note: See Section 13. "Output Compare" in the "dsPIC33F Family Reference Manual" (DS70209) for OCxR and OCxRS register restrictions.

"Motor Control PWM" (DS70187) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
* * * * * * * *
This module simplifies the task of generating multiple, synchronized Pulse-Width Modulated (PWM) outputs. In particular, the following power and motion control applications are supported by the PWM module: * * * * 3-Phase AC Induction Motor Switched Reluctance (SR) Motor Brushless DC (BLDC) Motor Uninterruptible Power Supply (UPS)
`On-the-fly' PWM frequency changes Edge and Center-Aligned Output modes Single Pulse Generation mode Interrupt support for asymmetrical updates in Center-Aligned mode Output override control for Electrically Commutative Motor (ECM) operation `Special Event' comparator for scheduling other peripheral events Fault pins to optionally drive each of the PWM output pins to a defined state Duty cycle updates are configurable to be immediate or synchronized to the PWM time base
This module contains four duty cycle generators, numbered 1 through 4. The module has eight PWM output pins, numbered PWM1H/PWM1L through PWM4H/PWM4L. The eight I/O pins are grouped into high/low numbered pairs, denoted by the suffix H or L, respectively. For complementary loads, the low PWM pins are always the complement of the corresponding high I/O pin. The PWM module allows several modes of operation which are beneficial for specific power control applications.
The PWM module has the following features: * Eight PWM I/O pins with four duty cycle generators * Up to 16-bit resolution

QUADRATURE ENCODER INTERFACE (QEI) MODULE
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 15. "Quadrature Encoder Interface (QEI)" (DS70208) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
The operational features of the QEI include the following: * Three input channels for two phase signals and an index pulse * 16-bit up/down position counter * Count direction status * Position Measurement (x2 and x4) mode * Programmable digital noise filters on inputs * Alternate 16-bit Timer/Counter mode * Quadrature Encoder Interface interrupts The QEI module's operating mode is determined by setting the appropriate bits, QEIM<2:0> (QEICON<10:8>). Figure 17-1 depicts the Quadrature Encoder Interface block diagram.
This section describes the Quadrature Encoder Interface (QEI) module and associated operational modes. The QEI module provides the interface to incremental encoders for obtaining mechanical position data.

SERIAL PERIPHERAL INTERFACE (SPI)
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 18. "Serial Peripheral Interface (SPI)" (DS70206) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
Note:
In this section, the SPI modules are referred to together as SPIx, or separately as SPI1 and SPI2. Special Function Registers will follow a similar notation. For example, SPIxCON refers to the control register for the SPI1 or SPI2 module.
Each SPI module consists of a 16-bit shift register, SPIxSR (where x = 1 or 2), used for shifting data in and out, and a buffer register, SPIxBUF. A control register, SPIxCON, configures the module. Additionally, a status register, SPIxSTAT, indicates various status conditions. The serial interface consists of 4 pins: SDIx (serial data input), SDOx (serial data output), SCKx (shift clock input or output) and SSx (active-low slave select). In Master mode operation, SCK is a clock output, but in Slave mode, it is a clock input.
The Serial Peripheral Interface (SPI) module is a synchronous serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, shift registers, display drivers, ADC, etc. The SPI module is compatible with SPI and SIOP from Motorola(R).

INTER-INTEGRATED CIRCUITTM (I2CTM)
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 19. "Inter-Integrated CircuitTM (I2CTM)" (DS70195) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
19.1
Operating Modes
The hardware fully implements all the master and slave functions of the I2C Standard and Fast mode specifications, as well as 7 and 10-bit addressing. The I2C module can operate either as a slave or a master on an I2C bus. The following types of I2C operation are supported: * * * I2C slave operation with 7-bit address I2C slave operation with 10-bit address I2C master operation with 7 or 10-bit address
The Inter-Integrated Circuit (I2C) module, with its 16-bit interface, provides complete hardware support for both Slave and Multi-Master modes of the I2C serial communication standard. The dsPIC33FJXXXMCX06/X08/X10 devices have up to two I2C interface modules, denoted as I2C1 and I2C2. Each I2C module has a 2-pin interface: the SCLx pin is clock and the SDAx pin is data. Each I2C module `x' (x = 1 or 2) offers the following key features: * I2C interface supports both master and slave operation. * I2C Slave mode supports 7- and 10-bit addresses. * I2C Master mode supports 7- and 10-bit addresses. * I2C Port allows bidirectional transfers between master and slaves. * Serial clock synchronization for the I2C port can be used as a handshake mechanism to suspend and resume serial transfer (SCLREL control). * I2C supports multi-master operation; it detects bus collision and will arbitrate accordingly.
For details about the communication sequence in each of these modes, please refer to the "dsPIC30F Family Reference Manual".
19.2
I2C Registers
I2CxCON and I2CxSTAT are control and status registers, respectively. The I2CxCON register is readable and writable. The lower six bits of I2CxSTAT are read-only. The remaining bits of the I2CSTAT are read/write. I2CxRSR is the shift register used for shifting data, whereas I2CxRCV is the buffer register to which data bytes are written, or from which data bytes are read. I2CxRCV is the receive buffer. I2CxTRN is the transmit register to which bytes are written during a transmit operation. The I2CxADD register holds the slave address. A status bit, ADD10, indicates 10-bit Address mode. The I2CxBRG acts as the Baud Rate Generator (BRG) reload value. In receive operations, I2CxRSR and I2CxRCV together form a double-buffered receiver. When I2CxRSR receives a complete byte, it is transferred to I2CxRCV and an interrupt pulse is generated.

Note:
The Universal Asynchronous Receiver Transmitter (UART) module is one of the serial I/O modules available in the dsPIC33FJXXXMCX06/X08/X10 device family. The UART is a full-duplex asynchronous system that can communicate with peripheral devices, such as personal computers, LIN, RS-232 and RS-485 interfaces. The module also supports a hardware flow control option with the UxCTS and UxRTS pins and also includes an IrDA(R) encoder and decoder. The primary features of the UART module are: * Full-Duplex, 8-bit or 9-bit Data Transmission through the UxTX and UxRX pins * Even, Odd or No Parity Options (for 8-bit data) * One or Two Stop bits

Note 1: Both UART1 and UART2 can trigger a DMA data transfer. If U1TX, U1RX, U2TX or U2RX is selected as a DMA IRQ source, a DMA transfer occurs when the U1TXIF, U1RXIF, U2TXIF or U2RXIF bit gets set as a result of a UART1 or UART2 transmission or reception. 2: If DMA transfers are required, the UART TX/RX FIFO buffer must be set to a size of 1 byte/word (i.e., UTXISEL<1:0> = 00 and URXISEL<1:0> = 00).

ENHANCED CAN (ECANTM) MODULE
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 21. "Enhanced Controller Area Network (ECANTM)" (DS70185) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
* Programmable link to input capture module (IC2 for both CAN1 and CAN2) for time-stamping and network synchronization * Low-power Sleep and Idle mode The CAN bus module consists of a protocol engine and message buffering/control. The CAN protocol engine handles all functions for receiving and transmitting messages on the CAN bus. Messages are transmitted by first loading the appropriate data registers. Status and errors can be checked by reading the appropriate registers. Any message detected on the CAN bus is checked for errors and then matched against filters to see if it should be received and stored in one of the receive registers.
21.1
Overview
21.2
Frame Types
The Enhanced Controller Area Network (ECANTM) module is a serial interface, useful for communicating with other CAN modules or microcontroller devices. This interface/protocol was designed to allow communications within noisy environments. The dsPIC33FJXXXMCX06/X08/X10 devices contain up to two ECAN modules. The CAN module is a communication controller implementing the CAN 2.0 A/B protocol, as defined in the BOSCH specification. The module will support CAN 1.2, CAN 2.0A, CAN 2.0B Passive and CAN 2.0B Active versions of the protocol. The module implementation is a full CAN system. The CAN specification is not covered within this data sheet. The reader may refer to the BOSCH CAN specification for further details. The module features are as follows: * Implementation of the CAN protocol, CAN 1.2, CAN 2.0A and CAN 2.0B * Standard and extended data frames * 0-8 bytes data length * Programmable bit rate up to 1 Mbit/sec * Automatic response to remote transmission requests * Up to eight transmit buffers with application specified prioritization and abort capability (each buffer may contain up to 8 bytes of data) * Up to 32 receive buffers (each buffer may contain up to 8 bytes of data) * Up to 16 full (standard/extended identifier) acceptance filters * Three full acceptance filter masks * DeviceNetTM addressing support * Programmable wake-up functionality with integrated low-pass filter * Programmable Loopback mode supports self-test operation * Signaling via interrupt capabilities for all CAN receiver and transmitter error states * Programmable clock source
The CAN module transmits various types of frames which include data messages, or remote transmission requests initiated by the user, as other frames that are automatically generated for control purposes. The following frame types are supported: * Standard Data Frame: A standard data frame is generated by a node when the node wishes to transmit data. It includes an 11-bit Standard Identifier (SID), but not an 18-bit Extended Identifier (EID). * Extended Data Frame: An extended data frame is similar to a standard data frame, but includes an extended identifier as well. * Remote Frame: It is possible for a destination node to request the data from the source. For this purpose, the destination node sends a remote frame with an identifier that matches the identifier of the required data frame. The appropriate data source node will then send a data frame as a response to this remote request. * Error Frame: An error frame is generated by any node that detects a bus error. An error frame consists of two fields: an error flag field and an error delimiter field. * Overload Frame: An overload frame can be generated by a node as a result of two conditions. First, the node detects a dominant bit during interframe space which is an illegal condition. Second, due to internal conditions, the node is not yet able to start reception of the next message. A node may generate a maximum of 2 sequential overload frames to delay the start of the next message. * Interframe Space: Interframe space separates a proceeding frame (of whatever type) from a following data or remote frame.

21.3 Modes of Operation
Note: The CAN module can operate in one of several operation modes selected by the user. These modes include: * * * * * * Initialization Mode Disable Mode Normal Operation Mode Listen Only Mode Listen All Messages Mode Loopback Mode Typically, if the CAN module is allowed to transmit in a particular mode of operation and a transmission is requested immediately after the CAN module has been placed in that mode of operation, the module waits for 11 consecutive recessive bits on the bus before starting transmission. If the user switches to Disable mode within this 11-bit period, then this transmission is aborted and the corresponding TXABT bit is set and TXREQ bit is cleared.
Modes are requested by setting the REQOP<2:0> bits (CiCTRL1<10:8>). Entry into a mode is Acknowledged by monitoring the OPMODE<2:0> bits (CiCTRL1<7:5>). The module will not change the mode and the OPMODE bits until a change in mode is acceptable, generally during bus Idle time, which is defined as at least 11 consecutive recessive bits.
21.3.3
NORMAL OPERATION MODE
Normal Operation mode is selected when REQOP<2:0> = 000. In this mode, the module is activated and the I/O pins will assume the CAN bus functions. The module will transmit and receive CAN bus messages via the CiTX and CiRX pins.
21.3.1
INITIALIZATION MODE
In the Initialization mode, the module will not transmit or receive. The error counters are cleared and the interrupt flags remain unchanged. The programmer will have access to Configuration registers that are access restricted in other modes. The module will protect the user from accidentally violating the CAN protocol through programming errors. All registers which control the configuration of the module can not be modified while the module is on-line. The CAN module will not be allowed to enter the Configuration mode while a transmission is taking place. The Configuration mode serves as a lock to protect the following registers: * * * * * All Module Control Registers Baud Rate and Interrupt Configuration Registers Bus Timing Registers Identifier Acceptance Filter Registers Identifier Acceptance Mask Registers
21.3.4
LISTEN ONLY MODE
If the Listen Only mode is activated, the module on the CAN bus is passive. The transmitter buffers revert to the port I/O function. The receive pins remain inputs. For the receiver, no error flags or Acknowledge signals are sent. The error counters are deactivated in this state. The Listen Only mode can be used for detecting the baud rate on the CAN bus. To use this, it is necessary that there are at least two further nodes that communicate with each other.
21.3.5
LISTEN ALL MESSAGES MODE
The module can be set to ignore all errors and receive any message. The Listen All Messages mode is activated by setting REQOP<2:0> = `111'. In this mode, the data which is in the message assembly buffer, until the time an error occurred, is copied in the receive buffer and can be read via the CPU interface.
21.3.2
DISABLE MODE
21.3.6
LOOPBACK MODE
In Disable mode, the module will not transmit or receive. The module has the ability to set the WAKIF bit due to bus activity, however, any pending interrupts will remain and the error counters will retain their value. If the REQOP<2:0> bits (CiCTRL1<10:8>) = 001, the module will enter the Module Disable mode. If the module is active, the module will wait for 11 recessive bits on the CAN bus, detect that condition as an Idle bus, then accept the module disable command. When the OPMODE<2:0> bits (CiCTRL1<7:5>) = 001, that indicates whether the module successfully went into Module Disable mode. The I/O pins will revert to normal I/O function when the module is in the Module Disable mode. The module can be programmed to apply a low-pass filter function to the CiRX input line while the module or the CPU is in Sleep mode. The WAKFIL bit (CiCFG2<14>) enables or disables the filter.
If the Loopback mode is activated, the module will connect the internal transmit signal to the internal receive signal at the module boundary. The transmit and receive pins revert to their port I/O function.

22.0 10-BIT/12-BIT ANALOG-TO-DIGITAL CONVERTER (ADC)
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 16. "Analog-to-Digital Converter (ADC)" (DS70183) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com). log input pins. The actual number of analog input pins and external voltage reference input configuration will depend on the specific device. Refer to the device data sheet for further details. A block diagram of the ADC is shown in Figure 22-1.
Note:
22.2
1.
ADC Initialization
The following configuration steps should be performed. Configure the ADC module: a) Select port pins as analog inputs (ADxPCFGH<15:0> or ADxPCFGL<15:0>) b) Select voltage reference source to match expected range on analog inputs (ADxCON2<15:13>) c) Select the analog conversion clock to match desired data rate with processor clock (ADxCON3<7:0>) d) Determine how many S/H channels will be used (ADxCON2<9:8> and ADxPCFGH<15:0> or ADxPCFGL<15:0>) e) Select the appropriate sample/conversion sequence (ADxCON1<7:5> and ADxCON3<12:8>) f) Select how conversion results are presented in the buffer (ADxCON1<9:8>) g) Turn on ADC module (ADxCON1<15>) Configure ADC interrupt (if required): a) Clear the ADxIF bit b) Select ADC interrupt priority
The dsPIC33FJXXXMCX06/X08/X10 devices have up to 32 ADC input channels. These devices also have up to 2 ADC modules (ADCx, where `x' = 1 or 2), each with its own set of Special Function Registers. The AD12B bit (ADxCON1<10>) allows each of the ADC modules to be configured by the user as either a 10-bit, 4-sample/hold ADC (default configuration) or a 12-bit, 1-sample/hold ADC. Note: The ADC module needs to be disabled before modifying the AD12B bit.
22.1
Key Features
The 10-bit ADC configuration has the following key features: * * * * * * * * * * Successive Approximation (SAR) conversion Conversion speeds of up to 1.1 Msps Up to 32 analog input pins External voltage reference input pins Simultaneous sampling of up to four analog input pins Automatic Channel Scan mode Selectable conversion trigger source Selectable Buffer Fill modes Four result alignment options (signed/unsigned, fractional/integer) Operation during CPU Sleep and Idle modes

22.3
ADC and DMA
If more than one conversion result needs to be buffered before triggering an interrupt, DMA data transfers can be used. Both ADC1 and ADC2 can trigger a DMA data transfer. If ADC1 or ADC2 is selected as the DMA IRQ source, a DMA transfer occurs when the AD1IF or AD2IF bit gets set as a result of an ADC1 or ADC2 sample conversion sequence. The SMPI<3:0> bits (ADxCON2<5:2>) are used to select how often the DMA RAM buffer pointer is incremented. The ADDMABM bit (ADxCON1<12>) determines how the conversion results are filled in the DMA RAM buffer area being used for ADC. If this bit is set, DMA buffers are written in the order of conversion. The module will provide an address to the DMA channel that is the same as the address used for the non-DMA stand-alone buffer. If the ADDMABM bit is cleared, then DMA buffers are written in Scatter/Gather mode. The module will provide a scatter/gather address to the DMA channel, based on the index of the analog input and the size of the DMA buffer.
The 12-bit ADC configuration supports all the above features, except: * In the 12-bit configuration, conversion speeds of up to 500 ksps are supported * There is only 1 sample/hold amplifier in the 12-bit configuration, so simultaneous sampling of multiple channels is not supported. Depending on the particular device pinout, the ADC can have up to 32 analog input pins, designated AN0 through AN31. In addition, there are two analog input pins for external voltage reference connections. These voltage reference inputs may be shared with other ana-

SPECIAL FEATURES
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 23. "CodeGuardTM Security" (DS70199), Section 24. "Programming and Diagnostics" (DS70207), and Section 25. "Device Configuration" (DS70194) in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
23.1
Configuration Bits
The Configuration bits can be programmed (read as `0'), or left unprogrammed (read as `1'), to select various device configurations. These bits are mapped starting at program memory location 0xF80000. The device Configuration register map is shown in Table 23-1. The individual Configuration bit descriptions for the FBS, FSS, FGS, FOSCSEL, FOSC, FWDT, FPOR and FICD Configuration registers are shown in Table 23-2. Note that address 0xF80000 is beyond the user program memory space. In fact, it belongs to the configuration memory space (0x800000-0xFFFFFF) which can only be accessed using table reads and table writes. The upper byte of all device Configuration registers should always be `1111 1111'. This makes them appear to be NOP instructions in the remote event that their locations are ever executed by accident. Since Configuration bits are not implemented in the corresponding locations, writing `1's to these locations has no effect on device operation. To prevent inadvertent configuration changes during code execution, all programmable Configuration bits are write-once. After a bit is initially programmed during a power cycle, it cannot be written to again. Changing a device configuration requires that power to the device be cycled.
dsPIC33FJXXXMCX06/X08/X10 devices include several features intended to maximize application flexibility and reliability, and minimize cost through elimination of external components. These are: * * * * * * Flexible Configuration Watchdog Timer (WDT) Code Protection and CodeGuardTM Security JTAG Boundary Scan Interface In-Circuit Serial ProgrammingTM (ICSPTM) In-Circuit Emulation

23.2 On-Chip Voltage Regulator 23.3 BOR: Brown-Out Reset
All of the dsPIC33FJXXXMCX06/X08/X10 devices power their core digital logic at a nominal 2.5V. This may create an issue for designs that are required to operate at a higher typical voltage, such as 3.3V. To simplify system design, all devices in the dsPIC33FJXXXMCX06/X08/X10 family incorporate an on-chip regulator that allows the device to run its core logic from VDD. The regulator provides power to the core from the other VDD pins. The regulator requires that a low-ESR (less than 5 ohms) capacitor (such as tantalum or ceramic) be connected to the VCAP/VDDCORE pin (Figure 23-1). This helps to maintain the stability of the regulator. The recommended value for the filter capacitor is provided in Table 26-13 of Section 26.1 "DC Characteristics". Note: It is important for the low-ESR capacitor to be placed as close as possible to the VCAP/VDDCORE pin. The BOR (Brown-out Reset) module is based on an internal voltage reference circuit that monitors the regulated supply voltage VCAP/VDDCORE. The main purpose of the BOR module is to generate a device Reset when a brown-out condition occurs. Brown-out conditions are generally caused by glitches on the AC mains (i.e., missing portions of the AC cycle waveform due to bad power transmission lines or voltage sags due to excessive current draw when a large inductive load is turned on). A BOR will generate a Reset pulse which will reset the device. The BOR will select the clock source, based on the device Configuration bit values (FNOSC<2:0> and POSCMD<1:0>). Furthermore, if an oscillator mode is selected, the BOR will activate the Oscillator Start-up Timer (OST). The system clock is held until OST expires. If the PLL is used, then the clock will be held until the LOCK bit (OSCCON<5>) is `1'. Concurrently, the PWRT time-out (TPWRT) will be applied before the internal Reset is released. If TPWRT = 0 and a crystal oscillator is being used, then a nominal delay of TFSCM = 100 is applied. The total delay in this case is TFSCM. The BOR Status bit (RCON<1>) will be set to indicate that a BOR has occurred. The BOR circuit continues to operate while in Sleep or Idle modes and will reset the device should VDD fall below the BOR threshold voltage.
On a POR, it takes approximately 20 s for the on-chip voltage regulator to generate an output voltage. During this time, designated as TSTARTUP, code execution is disabled. TSTARTUP is applied every time the device resumes operation after any power-down.

It is important for the low-ESR capacitor to be placed as close as possible to the VCAP/VDDCORE pin.

23.4 Watchdog Timer (WDT)
For dsPIC33FJXXXMCX06/X08/X10 devices, the WDT is driven by the LPRC oscillator. When the WDT is enabled, the clock source is also enabled. The nominal WDT clock source from LPRC is 32 kHz. This feeds a prescaler than can be configured for either 5-bit (divide-by-32) or 7-bit (divide-by-128) operation. The prescaler is set by the WDTPRE Configuration bit. With a 32 kHz input, the prescaler yields a nominal WDT time-out period (TWDT) of 1 ms in 5-bit mode, or 4 ms in 7-bit mode. A variable postscaler divides down the WDT prescaler output and allows for a wide range of time-out periods. The postscaler is controlled by the WDTPOST<3:0> Configuration bits (FWDT<3:0>) which allow the selection of a total of 16 settings, from 1:1 to 1:32,768. Using the prescaler and postscaler, time-out periods ranging from 1 ms to 131 seconds can be achieved. The WDT, prescaler and postscaler are reset: * On any device Reset * On the completion of a clock switch, whether invoked by software (i.e., setting the OSWEN bit after changing the NOSC bits) or by hardware (i.e., Fail-Safe Clock Monitor) * When a PWRSAV instruction is executed (i.e., Sleep or Idle mode is entered) * When the device exits Sleep or Idle mode to resume normal operation * By a CLRWDT instruction during normal execution If the WDT is enabled, it will continue to run during Sleep or Idle modes. When the WDT time-out occurs, the device will wake the device and code execution will continue from where the PWRSAV instruction was executed. The corresponding SLEEP or IDLE bits (RCON<3,2>) will need to be cleared in software after the device wakes up. The WDT flag bit, WDTO (RCON<4>), is not automatically cleared following a WDT time-out. To detect subsequent WDT events, the flag must be cleared in software. Note: The CLRWDT and PWRSAV instructions clear the prescaler and postscaler counts when executed.
The WDT is enabled or disabled by the FWDTEN Configuration bit in the FWDT Configuration register. When the FWDTEN Configuration bit is set, the WDT is always enabled. The WDT can be optionally controlled in software when the FWDTEN Configuration bit has been programmed to `0'. The WDT is enabled in software by setting the SWDTEN control bit (RCON<5>). The SWDTEN control bit is cleared on any device Reset. The software WDT option allows the user to enable the WDT for critical code segments and disable the WDT during non-critical segments for maximum power savings. Note: If the WINDIS bit (FWDT<6>) is cleared, the CLRWDT instruction should be executed by the application software only during the last 1/4 of the WDT period. This CLRWDT window can be determined by using a timer. If a CLRWDT instruction is executed before this window, a WDT Reset occurs.

Detailed information on the interface will be provided in future revisions of the document. When MPLAB(R) ICD 2 is selected as a debugger, the in-circuit debugging functionality is enabled. This function allows simple debugging functions when used with MPLAB IDE. Debugging functionality is controlled through the PGECx (Emulation/Debug Clock) and PGEDx (Emulation/Debug Data) pin functions. Any one out of three pairs of debugging clock/data pins may be used: * PGEC1 and PGED1 * PGEC2 and PGED2 * PGEC3 and PGED3 To use the in-circuit debugger function of the device, the design must implement ICSP connections to MCLR, VDD, VSS and the PGECx/PGEDx pin pair. In addition, when the feature is enabled, some of the resources are not available for general use. These resources include the first 80 bytes of data RAM and two I/O pins.
23.6
Code Protection and CodeGuardTM Security
The dsPIC33FJXXXMCX06/X08/X10 devices offer the advanced implementation of CodeGuardTM Security. CodeGuard Security enables multiple parties to securely share resources (memory, interrupts and peripherals) on a single chip. This feature helps protect individual Intellectual Property in collaborative system designs. When coupled with software encryption libraries, CodeGuard Security can be used to securely update Flash even when multiple IP are resident on the single chip. The code protection features vary depending on the actual device implemented. The following sections provide an overview of these features. The code protection features are controlled by the Configuration registers: FBS, FSS and FGS. Note: Refer to Section 23. "CodeGuardTM Security" (DS70199) in the "dsPIC33F Family Reference Manual" for further information on usage, configuration and operation of CodeGuard Security.
23.7
In-Circuit Serial Programming
dsPIC33FJXXXMCX06/X08/X10 family digital signal controllers can be serially programmed while in the end application circuit. This is simply done with two lines for clock and data and three other lines for power, ground and the programming sequence. This allows customers to manufacture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. This also allows the most recent firmware or a custom firmware, to be programmed. Please refer to the "dsPIC33F/PIC24H Flash Programming Specification" (DS70152) document for details about ICSP. Any one out of three pairs of programming clock/data pins may be used: * PGEC1 and PGED1 * PGEC2 and PGED2 * PGEC3 and PGED3

INSTRUCTION SET SUMMARY
This data sheet summarizes the features of the dsPIC33FJXXXMCX06/X08/X10 family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section in the "dsPIC33F Family Reference Manual", which is available from the Microchip web site (www.microchip.com).
Most bit-oriented instructions (including rotate/shift instructions) have two operands:
simple
* The W register (with or without an address modifier) or file register (specified by the value of `Ws' or `f') * The bit in the W register or file register (specified by a literal value or indirectly by the contents of register `Wb') The literal instructions that involve data movement may use some of the following operands: * A literal value to be loaded into a W register or file register (specified by the value of `k') * The W register or file register where the literal value is to be loaded (specified by `Wb' or `f') However, literal instructions that involve arithmetic or logical operations use some of the following operands: * The first source operand which is a register `Wb' without any address modifier * The second source operand which is a literal value * The destination of the result (only if not the same as the first source operand) which is typically a register `Wd' with or without an address modifier The MAC class of DSP instructions may use some of the following operands: * The accumulator (A or B) to be used (required operand) * The W registers to be used as the two operands * The X and Y address space prefetch operations * The X and Y address space prefetch destinations * The accumulator write back destination The other DSP instructions do not involve any multiplication and may include: * The accumulator to be used (required) * The source or destination operand (designated as Wso or Wdo, respectively) with or without an address modifier * The amount of shift specified by a W register `Wn' or a literal value The control instructions may use some of the following operands: * A program memory address * The mode of the table read and table write instructions
The dsPIC33F instruction set is identical to that of the dsPIC30F. Most instructions are a single program memory word (24 bits). Only three instructions require two program memory locations. Each single-word instruction is a 24-bit word, divided into an 8-bit opcode, which specifies the instruction type and one or more operands, which further specify the operation of the instruction. The instruction set is highly orthogonal and is grouped into five basic categories: * * * * * Word or byte-oriented operations Bit-oriented operations Literal operations DSP operations Control operations
Table 24-1 shows the general symbols used in describing the instructions. The dsPIC33F instruction set summary in Table 24-2 lists all the instructions, along with the status flags affected by each instruction. Most word or byte-oriented W register instructions (including barrel shift instructions) have three operands: * The first source operand which is typically a register `Wb' without any address modifier * The second source operand which is typically a register `Ws' with or without an address modifier * The destination of the result which is typically a register `Wd' with or without an address modifier However, word or byte-oriented file register instructions have two operands: * The file register specified by the value `f' * The destination, which could either be the file register `f' or the W0 register, which is denoted as `WREG'

dsPIC33FJXXXMCX06/X08/X10
All instructions are a single word, except for certain double-word instructions, which were made double-word instructions so that all the required information is available in these 48 bits. In the second word, the 8 MSbs are `0's. If this second word is executed as an instruction (by itself), it will execute as a NOP. Most single-word instructions are executed in a single instruction cycle, unless a conditional test is true, or the program counter is changed as a result of the instruction. In these cases, the execution takes two instruction cycles with the additional instruction cycle(s) executed as a NOP. Notable exceptions are the BRA (unconditional/computed branch), indirect CALL/GOTO, all table reads and writes and RETURN/RETFIE instructions, which are single-word instructions but take two or three cycles. Certain instructions that involve skipping over the subsequent instruction require either two or three cycles if the skip is performed, depending on whether the instruction being skipped is a single-word or two-word instruction. Moreover, double-word moves require two cycles. The double-word instructions execute in two instruction cycles. Note: For more details on the instruction set, refer to the "dsPIC30F/33F Programmer's Reference Manual" (DS70157).

Data in "Typ" column is at 3.3V, 25C unless otherwise stated. Instruction cycle period (TCY) equals two times the input oscillator time-base period. All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at "min." values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the "max." cycle time limit is "DC" (no clock) for all devices. Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin. Data for this parameter is Preliminary. This parameter is characterized, but not tested in manufacturing.

Timing Parameters
These parameters are characterized but not tested in manufacturing. Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity performance, especially at elevated temperatures. tDPU is the time required for the ADC module to stabilize when it is turned on (AD1CON1 = 1). During this time, the ADC result is indeterminate.
