all v dd and v ss pins (see section 2.2 ?decoupling capacitors? ) ? all av dd and av ss pins, regardless if adc module is not used (see section 2.2 ?decoupling capacitors? ) ?v cap (see section 2.3 ?capacitor on internal voltage regulator (v cap )? ) ?mclr pin (see section 2.4 ?master clear (mclr) pin? ) ? pgecx/pgedx pins used for in-circuit serial programming? (icsp?) and debugging purposes (see section 2.5 ?icsp? pins? ) ? osc1 and osc2 pins when external oscillator source is used (see section 2.6 ?externa l oscillator pins? ) 2.2 decoupling capacitors the use of decoupling capacitors on every pair of power supply pins, such as v dd , v ss , av dd and av ss , 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 1: this data sheet summ arizes the features of the dspic33fj 06gs001/101a/102a/ 202a and dspic33fj09gs302 family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?

for additional information. the placement of this capacitor should be close to the v cap . it is recommended that the trace length not exceed one-quarter inch (6 mm). refer to section 22.2 ?on-chip voltage regulator? for details. 2.4 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 (v ih and v il ) and fast signal transitions must not be adve rsely 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. figure 2-2: example of mclr pin connections dspic33f v dd v ss v dd v ss v ss v dd av dd av ss v dd v ss 0.1 f ceramic 0.1 f ceramic 0.1 f ceramic 0.1 f ceramic c r v dd mclr 0.1 f ceramic v cap l1 (1) r1 10 f tantalum note 1: as an option, instead of a hard-wired connection, an inductor (l1) can be substituted between v dd and av dd to improve adc noise rejection. the inductor impedance should be less than 1 ?

(icsp?) 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 communi- cations 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 tim- ing requirements information in the respective device flash programming specification for information on capacitive loading limits, and input voltage high (v ih ) and input voltage low (v il ) pin 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 ? icd 3 or mplab real ice?. for more information on mplab icd 3 and real ice connection requirements, refer to the following documents that are available on the microchip web site ( www.microchip.com ): ? ?using mplab ? icd 3?

(poster) (ds51749) 2.6 external oscillator pins many dscs have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to section 8.0 ?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 t he 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 wher e the crystal is placed. a suggested layout is shown in figure 2-3 . figure 2-3: suggested placement of the oscillator circuit 13 main oscillator guard ring guard trace secondary oscillator 14 15 16 17 18 19 20 dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 20 ? 2011-2012 microchip technology inc. 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 < f in < 8 mhz to comply with device pll start-up conditions. this means that if the external oscillator frequency is outside of this range, the application must start up in the frc mode first. the default pll settings after a por, with an oscillator frequency outside of 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 3 or real ice is selected as a debug- ger, it automatically initializes all of the analog-to-digital input pins (anx) as ?digital? pins, by setting all bits in the adpcfg register. the bits in the registers that correspond to the analog-to-digital pins that are initialized by mplab 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 analog-to-digital pins as analog input pins during the debug session, the user application must clear the corresponding bits in the adpcfg register during initialization of the adc module. when mplab icd 3 or real ice is used as a programmer, the user application firmware must correctly configure the adpcfg register. automatic initialization of these registers is only done during debugger operation. failure to correctly configure the register(s) will result in all analog-to-digital 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 between v ss and unused pins, and drive the output to logic low. 2.10 typical application connection examples examples of typical application connections are shown in figure 2-4 through figure 2-8 . ?

(ds70157) for information on the sr bits affected by each instruction. the cpu incorporates hardware support for both multipli- cation and division. this includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 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: ? 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 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: ? 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 dsp engine 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 dspic33fj06gs001/101a/102a/202a and dspic33fj09gs302 devices feature 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 can be used concurrently by the same instruction (for example, ed, edac). the dsp engine can also perform inherent accumulator-to-accumulator operations that require no additional data. these instructions are add, sub and neg . the dsp engine has options selected through bits in the cpu core control register (corcon), as listed below: ? 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) ?

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 2?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 2?s complement fraction with this implied radix point is -1.0 to (1 ? 2 1-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 that has a pr ecision 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 multiply operations. the mul instruction can 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. 3.6.2 data accumulators and adder/subtracter 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 accumu- lated or loaded can be optionally scaled using the barrel shifter prior to accumulation. 3.6.2.1 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/b orrow input is active-high and the other input is true data (not complemented) ? 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 that controls accumulator data saturation, if selected. it uses the result of the adder, the overflow status bits described previously and the sat dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 34 ? 2011-2012 microchip technology inc. 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). programmers can 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 is useful for complex number arithmetic, which typically uses both accumulators. the device supports three saturation and overflow modes: ? 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 accumu- lator. the sa or sb bit is set and remains set until cleared by the user application. this condition is referred to as ?super saturation? and provides protection against erroneous data or unexpected algorithm problems (such as 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 accumu- lator. the sa or sb bit is set and remains set until cleared by the user application. when this satura- tion mode is in effect, the guard bits are not used, so the oa, ob or oa b bits are never set. ? bit 39 catastrophic overflow: 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 application. 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. 3.6.3 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 no t 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: ? w13, register direct: the rounded contents of the non-target accumulator are written into w13 as a 1.15 fraction. ? [w13] + = 2, register i ndirect 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). 3.6.3.1 round logic the round logic is a combinational block that 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 that is pass ed 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 accu- mulator 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 al gorithm 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 3.6.3.2 ?data space write saturation? ). for the mac class of instructions, the accumulator write- back operation functions 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.?

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 t he source (bit 39) is used to determine the sign of the operand being tested. if the satdw bit in the corco n register is not set, the input data is always passed through unmodified under all conditions. 3.6.4 barrel shifter the barrel shifter can perform 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 and 31 for right shifts, and between bit positions 0 and 15 for left shifts. dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 36 ?

. user application 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 constant current source trim value and device id sections of the configuration memory space. the device memory maps are shown in figure 4-1 . figure 4-1: program memory maps for dspic33fj06gs001/101a/102a/202a and dspic33fj09gs302 devices note: this data sheet summ arizes the features of the dspic33fj 06gs001/101a/102a/ 202a and dspic33fj09gs302 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 4. ?program memory?

2011-2012 microchip technology inc. 4.1.1 program memory organization 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 (see figure 4-2 ). program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented by two during the code execution. this arrangement provides compatibility with data memory space addressing and makes data in the program memory space accessible. 4.1.2 interrupt and trap vectors all devices reserve the addresses between 0x00000 and 0x000200 for hard-coded program execution vectors. a hardware reset vector is provided to redirect code execu- tion from the default value of the pc on device reset to the actual start of code. a goto instruction is pro- grammed by the user applic ation at 0x000000, with the actual address for the st art of code at 0x000002. the devices also have two interrupt vector tables, located from 0x000004 to 0x0000ff and 0x000100 to 0x0001ff. these vector tables allow each of the 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?

). all devices implement up to 1 kbyte of data memory. should an ea point to a location outside of this area, an all-zero word or byte will be returned. 4.2.1 data space width 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 (lsbs) of each word have even addresses, while the most significant bytes (msbs) have odd addresses. 4.2.2 data memory organization and alignment to maintain backward compatibility with pic ? mcu devices and improve data space memory usage efficiency, the instruction se t supports both word and byte operations. as a consequence of byte accessibil- ity, all effective address calculations are internally scaled to step through word-aligned memory. for example, the core recognizes post-modified register indirect addressing mode [ws++], which results 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 reg- isters are organized as two parallel byte-wide entities with shared (word) address de code but separate write lines. data byte writes only write to the corresponding side of the array or register that matches the byte address. 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 e rror occurred on a read, the instruction underway is completed. if the error occurred on a write, the instruction is executed but the write does not occur. in either case, a trap is then executed, allowing the system and/or user application 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 ( se ) instruction is provided to allow user applications to translate 8-bit signed data to 16-bit signed values. alternatively, for 16-bit unsigned data, user applications can clear the msb of any w register by executing a zero-extend ( ze ) instruction on the appropriate address. 4.2.3 sfr space 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 core and peripheral modules for controlling the operation of the device. sfrs are distributed amon g 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 ?. 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. note: the actual set of peripheral features and interrupts varies by the device. refer to the corresponding device tables and pinout diagrams for device-specific information. dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 40 ?

2011-2012 microchip technology inc. 4.2.5 x and y data spaces 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. x data space has separate read and write data buses. 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, included 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. ?

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. fo r example, to cause a stack error trap when the stack grows beyond address 0x1000 in ram, initialize the splim with the value 0x0ffe. 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. figure 4-5: call stack frame 4.4 instruction addressing modes the addressing modes shown in table 4-39 form the basis of the addressing modes optimized to support the specific features of i ndividual instructions. the addressing modes provided in the mac class of instructions differ from th ose in the other instruction types. 4.4.1 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. 4.4.2 mcu instructions the three-operand mcu instru ctions are of the form: operand 3 = operand 1 ?

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 4.4.4 mac instructions the dual source operand dsp instructions ( clr , ed , edac , mac , mpy , mpy.n , movsac and msc ), also referred to as mac instructions, use a simp lified set of addressing modes to allow the user application to effectively manipulate the data pointers through register indirect tables. the two-source operand pref etch 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 are always 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. 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) 4.4.5 other instructions besides the addressing modes outlined previously, some instructions use literal cons tants 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. addressing mode description file register direct the address of the file register is specified explicitly. register direct the contents of a register are accessed directly. register indirect the contents of wn forms the effective address (ea). register indirect post-modified the contents of wn forms the ea. wn is post-modified (incremented or decremented) by a constant value. register indirect pre-modified wn is pre-modified (inc remented or decremented) by a signed constant value to form the ea. register indirect with register offset (register indexed) the sum of wn and wb forms the ea. register indirect with literal offset the sum of wn and a literal forms the ea. 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 by both source and destination (but typically only used by one). note: not all instructions support all the addressing modes given above. individual instructions may support different subsets of these addressing modes. note: register indirect with register offset addressing mode is available only for w9 (in x space) and w11 (in y space). dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 68 ? 2011-2012 microchip technology inc. 4.5 modulo addressing modulo addressing mode is a method used to provide 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 circ ular buffer can be supported in each of the x (which also provides the pointers into program space) and y data spaces. modulo addressing can operate on any w register pointer. however, it is not advisable to use w14 or w15 for modulo addressing since these two registers ar e used as the stack frame pointer and stack pointer, respectively. in general, any particular circular buffer can be configured to operate in only one direction as there are certain restrictions on th e 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 that have a power-of-two length. as these buffers satisfy the start and end address criteria, they can operate in a bidirectional mode (that is, address boundary checks are performe d on both the lower and upper address boundaries). 4.5.1 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 ta b l e 4 - 1 ). 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). 4.5.2 w address register selection the modulo and bit-reversed addressing control register, modcon<15:0>, contains enable flags as well as a w register fiel d to specify the w address registers. the xwm and ywm fields select the registers that will operat e with modulo addressing: ? if xwm = 15, x ragu and x wagu modulo addressing is disabled ? 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>. figure 4-6: modulo addr essing operation example note: y space modulo addressing ea calculations assume word-sized data (lsb of every ea is always clear). 0x1100 0x1163 start addr = 0x1100 end addr = 0x1163 length = 32 words byte address mov #0x1100, w0 mov w0, xmodsrt ;set modulo start address mov #0x1163, w0 mov w0, modend ;set modulo end address mov #0x8001, w0 mov w0, modcon ;enable w1, x agu for modulo mov #0x0000, w0 ;w0 holds buffer fill value mov #0x1110, w1 ;point w1 to buffer do again, #0x31 ;fill the 50 buffer locations mov w0, [w1++] ;fill the next location again: inc w0, w0 ;increment the fill value ?

upper boundary addresses for incrementing buffers ? lower boundary addresses for decrementing buffers 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 can, therefore, jump beyond boundaries and still be adjusted correctly. 4.6 bit-reversed addressing bit-reversed addressing mode is intended to simplify data re-ordering for radix-2 fft algorithms. it is supported by the x agu for data writes only. the modifier, which can 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. 4.6.1 bit-reversed addressing implementation bit-reversed addressing mode is enabled when all of these conditions are met: ? bwmx bits (w register selection) in the modcon register are any value other than ?15? (the stack cannot be accessed using bit-reversed addressing) ? bren bit is set in the xbrev register ? addressing mode used is register indirect with pre-increment or post-increment if the length of a bit-reversed buffer is m = 2 n 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 typica lly a constant. in the case of an fft computation, its value is equal to half of the fft data buffer size. when enabled, bit-reversed addressing is executed only 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, and normal addresses are generated instead. when bit-reversed ad dressing is active, the w address pointer is always added to the address modifier (xb), and the offs et associated with the regis- ter indirect addressing mode is ignored. in addition, as word-sized data is a requirement, the lsb of the ea is ignored (and always clear). if bit-reversed addressing has already been enabled by setting the bren (xbrev<15>) bit, 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. 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 (such as [w7 + w2]) is used, modulo addressing correction is performed but the contents of the register remain unchanged. 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. note: modulo addressing and bit-reversed addressing should not be enabled together. if an application attempts to do so, bit-reversed addressing will assume priority when active for the x wagu and x wagu; modulo addressing will be dis- abled. however, modulo addressing will continue to function in the x ragu. dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 70 ?

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 periodically. 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. the application can only access the least significant word of the program word. 4.7.1 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 (psvp ag) 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 4-41 and figure 4-8 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, and d<15:0> refers to a data space word. table 4-41: program space address construction access type access space program space address <23> <22:16> <15> <14:1> <0> instruction access (code execution) user 0 pc<22:1> 0 0xx xxxx xxxx xxxx xxxx xxx0 tblrd/tblwt (byte/word read/write) user tblpag<7:0> data ea<15:0> 0xxx xxxx xxxx xxxx xxxx xxxx configuration tblpag<7:0> data ea<15:0> 1xxx xxxx xxxx xxxx xxxx xxxx program space visibility (block remap/read) user 0 psvpag<7:0> data ea<14:0> ( 1 ) 0 xxxx xxxx xxx xxxx xxxx xxxx note 1: data ea<15> is always ?

tblrdl (table read low): - in word mode, this instruction 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 ?. ? tblrdh ( table read high): - in word mode, this instruction 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, this inst ruction maps the upper or lower byte of the program word to d<7:0> of the data address, in the tblrdl instruction. the data is always ? 0 ? when the upper ?phantom? byte is selected (byte select = 1 ). similarly, 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. figure 4-9: accessing program memory with table instructions 0 8 16 23 00000000 00000000 00000000 00000000 ?phantom?

2011-2012 microchip technology inc. 4.7.3 reading data from program memory using program space visibility 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 to stored constant data from the data space without the need to use special instructions (such as tblrdl or tblrdh ). 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. 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 ad d a cycle to the instruction being executed, since two program memory fetches are required. although each data space address 0x8000 and higher maps directly into a corresponding program memory address (see figure 4-10 ), only the lower 16 bits of the 24-bit program word are us ed 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. for operations that use psv and are executed outside a repeat loop, the mov and mov.d instructions require one instruction cycle in ad dition 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, these instances require two instruction cycles in addition to the spec ified execution time of the instruction: ? execution in th e 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 using psv to access data, to execute in a single cycle. figure 4-10: program space visibility operation note: psv access is temporar ily disabled during table reads/writes. 23 15 0 psvpag data space program space 0x0000 0x8000 0xffff 02 0x000000 0x800000 0x010000 0x018000 when corcon<2> = 1 and ea<15> = 1 : the data in the page designated by psvpag is mapped into the upper half of the data memory space... data ea<14:0> ...while the lower 15 bits of the ea specify an exact address within the psv area. this corresponds exactly to the same lower 15 bits of the actual program space address. psv area ?

(icsp?) programming capability ? run-time self-programming (rtsp) icsp allows a dspic33f j06gs001/101a/102a/202a and dspic33fj09gs302 device to be serially programmed while in the end application circuit. this is 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 (v dd ), ground (v ss ) and master clear (mclr ). 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. rtsp is accomplished using tblrd (table read) and tblwt (table write) instructions. with rtsp, the user application can write a single program memory word at a time, and erase program memory in blocks or ?pages? of 512 instructions (1536 bytes) at a time. 5.1 table instructions and flash programming regardless of the method used, all programming of flash memory is done with the table read and table write instructions. these al low 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 the 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. figure 5-1: addressing for table registers note 1: this data sheet summ arizes the features of the dspic33fj06gs001/101a/ 102a/202a and dspic33fj09gs302 families of devices. it is not intended to be a comprehensive reference source. to complement the informa- tion in this data sheet, refer to section 5. ?flash programming?

cold reset ? warm reset a cold reset is the result of a power-on reset (por) or a brown-out reset (bor). on a cold reset, the fnosc configuration bits in the fosc configuration register select the device clock source. a warm reset is the result of all the other reset sources, including the reset instruction. on warm reset, the device will continue to operate from the current clock source, as indicated by the current oscillator selection bits (cosc<2:0>) in the oscillator control register (osccon<14:12>). the device is kept in a reset state until the system power supplies have stabilized at appropriate levels and the oscillator clock is ready. the sequence in which this occurs is provided in figure 6-2 . table 6-1: oscillator delay oscillator mode oscillator start-up delay oscillator start-up timer pll lock time total delay frc, frcdiv16, frcdivn t oscd ( 1 ) ??

for more information. 5: when the oscillator clock is ready, the processor begins execut ion from location, 0x000000. the user application programs a goto instruction at the reset address, which redirects program execution to the appropriate start-up routine. 6: if the fail-safe clock monitor (fscm) is enabled, it begins to monitor the system clock when the system clock is ready and the delay, t fscm , has elapsed. table 6-2: oscillator parameters symbol parameter value v por por threshold 1.8v nominal t por por extension time 30 ?

2011-2012 microchip technology inc. 6.3 power-on reset (por) a power-on reset (por) circuit ensures the device is reset from power-on. the por circuit is active until v dd crosses the v por threshold and the delay, t por , has elapsed. the delay, t por , ensures the internal device bias circuits become stable. the device supply voltage characteristics must meet the specified starting voltage and rise rate requirements to generate the por. refer to section 25.0 ?electrical characteristics? for details. the por status (por) bit in the reset control (rcon<0>) register is set to indicate the power-on reset. 6.4 brown-out reset (bor) and power-up timer (pwrt) the on-chip regulator has a brown-out reset (bor) circuit that resets the device when the v dd is too low (v dd < v bor ) for proper device operation. the bor circuit keeps the device in reset until v dd crosses the v bor threshold and the delay, t bor , has elapsed. the delay, t bor , ensures the voltage regulator output becomes stable. the bor status bit in t he reset control (rcon<1>) register is set to indi cate the brown-out reset. the device will not run at full speed after a bor, as the v dd should rise to acceptab le levels for full-speed operation. the pwrt provides a power-up time delay (t pwrt ) to ensure that the system power supplies have stabilized at the appropriate levels for full-speed operation before the sysrst is released. figure 6-3 shows the typical brown-out scenarios. the reset delay (t bor + t pwrt ) is initiated each time v dd rises above the v bor trip point. figure 6-3: brown-out situations v dd sysrst v bor v dd sysrst v bor v dd sysrst v bor t bor + t pwrt v dd dips before pwrt expires t bor + t pwrt t bor + t pwrt ?

for minimum pulse width specifications. the external reset (mclr ) pin (extr) bit in the reset control (rcon) register is set to indicate the mclr reset. 6.5.1 external supervisory circuit many systems have external supervisory circuits that generate reset signals to reset multiple devices in the system. this external reset signal can be directly connected to the mclr pin to reset the device when the rest of the system is reset. 6.5.2 internal supervisory circuit when using the internal power supervisory circuit to reset the device, the external reset pin (mclr ) should be tied directly or resistively to v dd . in this case, the mclr pin will not be used to generate a reset. the external reset pin (mclr ) does not have an internal pull-up and must not be left unconnected. 6.6 software reset instruction (swr) whenever the reset instruction is executed, the device will assert sysrst , placing the device in a special reset state. this reset state will not re-initialize the clock. the clock source in effect prior to the reset instruction will still remain. sysrst is released at the next instruction cycle and the reset vector fetch will commence. the software reset (swr) flag (instruction) in the reset control register (rcon<6>) is set to indicate the software reset. 6.7 watchdog time-out reset (wdto) whenever a watchdog timer time-out occurs, the device will asynchronously assert sysrst . the clock source will remain unchanged. a wdt time-out during sleep or idle mode will wake-up the processor, but will not reset the processor. the watchdog timer time-out (wdto) flag in the reset control (rcon<4>) register is set to indicate the watchdog timer reset. refer to section 22.4 ?watchdog timer (wdt)? for more information on watchdog reset. 6.8 trap conflict reset if a lower priority hard trap occurs, while a higher priority trap is being processed, a hard trap conflict reset occurs. the hard traps include exceptions of priority level 13 through level 15, inclusive. the address error (level 13) and oscillator error (level 14) traps fall into this category. the trap reset (trapr) flag in the reset control register (rcon<15>) is set to indicate the trap conflict reset. refer to section 7.0 ?interrupt controller? for more information on tr ap conflict resets. 6.9 illegal condition device reset an illegal condition device reset occurs due to the following sources: ? illegal opcode reset ? uninitialized w register reset ? security reset the illegal opcode or uninitialized w access reset (iopuwr) flag in the reset control register (rcon<14>) is set to indicate the illegal condition device reset. 6.9.1 illegal opcode reset a device reset is generated if the device attempts to execute an illegal opcode value that is fetched from program memory. the illegal opcode reset function can prevent the device from executing program memory sections that are used to store constant data. to take advantage of the illegal opcode reset, use only the lower 16 bits of each program memory section to store the data values. the upper 8 bits should be programmed with 0x3f, which is an illegal opcode value. 6.9.2 uninitializ ed w register reset any attempt to use the unin itialized w register as an address pointer will reset the device. the w register array (with the exception of w15) is cleared during all resets and is considered un initialized until written to. dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 86 ?

up to eight processor exceptions and software traps ? seven user-selectable priority levels ? interrupt vector table (i vt) 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 7.1 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 non-maskable 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. lower addresses generally have a higher natural priority. for example, the interrupt associated with vector 0 will take priority over interrupts at any other vector address. the devices implement up to 28 unique interrupts and four non-maskable traps. these are summarized in table 7-1 . 7.1.1 alternate interrupt vector ta b l e 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 vector s. 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 feat ure 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. 7.2 reset sequence a device reset is not a tr ue exception because the interrupt controller is not involved in the reset process. a 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. a goto instruction at the reset address can redirect program execution to the approp riate start-up routine. note 1: this data sheet summ arizes the features of the dspic33fj 06gs001/101a/102a/ 202a and dspic33fj09gs302 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 41. ?interrupts (part iv)?

2011-2012 microchip technology inc. 7.3 interrupt control and status registers the following registers are implemented for the interrupt controller: ? intcon1 ? intcon2 ?ifsx ?iecx ?ipcx ?inttreg 7.3.1 intcon1 and intcon2 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 contro ls the external interrupt request signal behavior and the use of the alternate interrupt vector table. 7.3.2 ifsx the ifsx 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. 7.3.3 iecx the iecx registers maintain all of the interrupt enable bits. these control bits are used to individually enable interrupts from the peripherals or external signals. 7.3.4 ipcx the ipcx registers are used to set the interrupt priority level (ipl) for each source of interrupt. each user interrupt source can be assigned to one of eight priority levels. 7.3.5 inttreg the inttreg register contains the associated interrupt vector number and the new cp u interrupt priority level, which are latched into the 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 ta b l e 7 - 1 . for example, the int0 (external interrupt 0) is shown as hav ing vector number 8 and a natural order priority of 0. thus, the int0if bit is found in ifs0<0>, the int0ie bit is found in iec0<0> and the int0ip bits are found in the first position of ipc0 (ipc0<2:0>). 7.3.6 status/control registers although they are not specific ally part of the interrupt control hardware, two of the cpu control registers contain bits that contro l interrupt functionality. ? the cpu status register, sr, contains the ipl<2:0> bits (sr<7:5>). these bits indicate the current cpu interrupt prio rity 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>, 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 7-35 . ?

2011-2012 microchip technology inc. 7.4 interrupt setup procedures 7.4.1 initialization complete the following steps to configure an interrupt source at initialization: 1. set the nstdis bit (intcon1<15>) if nested interrupts are not desired. 2. 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 can be programmed to the same non-zero value. 3. clear the interrupt flag status bit associated with the peripheral in the associated ifsx register. 4. 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 used to declare an isr and initialize the ivt with the correct vector address depends on the programming language (c or assembler) and the language development toolsuite used to develop the application. in general, the user application must clear the interrupt flag in the appropriate ifsx register for the source of the interrupt that the isr handles; otherwise, the pro- gram will re-enter the isr i mmediately 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 the old cpu priority level. 7.4.3 trap service routine 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 the following steps outline t he procedure to disable all user interrupts: 1. push the current sr value onto the software stack using the push instruction. 2. force the cpu to priority level 7 by inclusive oring the value, 0xe0 with srl. to enable user interrupts, the pop instruction can be used to restore the previous sr value. 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. note: at a device reset, the ipcx registers are initialized such that all user interrupt sources are assigned to priority level 4. note: only user interrupts with a priority level of 7 or lower can be disabled. trap sources (level 8-level 15) cannot be disabled. ?

(refer to section 22.1 ?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, 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 among 12 different clock modes, shown in table 8-1 . the output of the oscillator (or the output of the pll if a pll mode has been selected), f osc , is divided by 2 to generate the device instruction clock (f cy ) and the peripheral clock time base (f p ). f cy defines the operating speed of the device and speeds up to 40 mhz are supported by the device architecture. instruction execution speed or device operating frequency, f cy , is given by equation 8-1 . equation 8-1: device operating frequency table 8-1: configuration bit values for clock selection f cy = f osc /2 oscillator mode oscillator source poscmd<1:0> fnosc<2:0> see note fast rc oscillator with div ide-by-n (frcdivn) internal xx 111 1 , 2 fast rc oscillator with divide-by-16 (frcdiv16) internal xx 110 1 low-power rc oscillator (lprc) internal xx 101 1 reserved reserved xx 100 ?

can be either 2, 4, or 8, and must be selected such that the pll output frequency (f osc ) 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 ?f in ?, the pll output ?f osc ?, is given by equation 8-2 . equation 8-2: f osc calculation for example, suppose a 10 mhz crystal is being used with the selected oscillator mode of xt with pll (see equation 8-3 ). ? 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 x 32 = 160 mhz, which is within the 100-200 mhz ranged needed. ? if pllpost<1:0> = 00 , then n2 = 2. this pro- vides a f osc of 160/2 = 80 mhz. the resultant device operating speed is 80/2 = 40 mips. equation 8-3: xt with pll mode example 8.2 auxiliary clock generation the auxiliary clock generation is used for a peripherals that need to operate at a frequency unrelated to the system clock, such as a pwm or adc. the primary oscillator and internal frc oscillator sources can be used with an auxiliary pll to obtain the auxiliary clock. the auxiliary pll has a fixed 16x multiplication factor. the auxiliary clock has the following configuration restrictions: ? for proper pwm operation, auxiliary clock genera- tion must be configured for 120 mhz (see parameter os56 in table 25-18 in section 25.0 ?electrical ch aracteristics? ). if a slower frequency is desired, the pwm input clock prescaler (divider) select bits (pclkdiv<2:0>) should be used. ? to achieve 1.04 ns pwm resolution, the auxiliary clock must use the 16x auxiliary pll (apll). all other clock sources will have a minimum pwm resolution of 8 ns. ? if the primary pll is used as a source for the auxiliary clock, the primary pll should be configured up to a maximum operation of 30 mips or less 8.3 reference clock generation the reference clock output logic provides the user with the ability to output a clock signal based on the system clock or the crystal oscillator on a device pin. the user application can specify a wide range of clock scaling prior to outputting the reference clock. figure 8-2: dspic33fj06gs001/101a/102a/202a and dspic33fj09gs302 pll block diagram ( ) m n 1 * n 2 f osc = f in * f cy = f osc 2 == 1 2 ( 10000000 * 32 2 * 2 ) 40 mips 0.8-8.0 mhz here (1) 100-200 mhz here (1) divide by 2, 4, 8 divide by 2-513 divide by 2-33 source (crystal, external pllpre x vco plldiv pllpost clock or internal rc) 12.5-80 mhz here (1) f osc f vco n1 m n2 note 1: this frequency range must be satisfied at all times. dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 126 ?

2011-2012 microchip technology inc. 8.5 clock switching operation applications are free to s witch among any of the four clock sources (primary, lp, frc and lprc) under software control at any time . to limit the possible side effects of this flexibility, devices have a safeguard lock built into the switch process. 8.5.1 enabling clock switching to enable clock switching, the fcksm1 configuration bit in the fosc configuration register must be programmed to ? 0 ?. (refer to section 22.1 ?configuration bits? for further details.) if the fcksm1 configuration bit is unpro- grammed (? 1 ?), the clock switching function and fail-safe clock monitor function are di sabled. this is the default setting. the nosc<2:0> control bits (osccon<10:8>) do not control the clock selection when clock switching is disabled. however, the cosc<2:0> 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. 8.5.2 oscillator switching sequence to perform a clock switch, the following basic sequence is required: 1. if desired, read the cosc<2:0> bits to determine the current oscillator source. 2. perform the unlock sequence to allow a write to the osccon register high byte. 3. write the appropriate value to the nosc<2:0> control bits for the new oscillator source. 4. perform the unlock sequence to allow a write to the osccon register low byte. 5. set the oswen bit (osccon<0>) to initiate the oscillator switch. once the basic sequence is completed, the system clock hardware responds automatically as follows: 1. the clock switching ha rdware compares the cosc<2:0> status bits with the new value of the nosc<2:0> control bits. if they are the same, the clock switch is a redu ndant operation. in this case, the oswen bit is cleared automatically and the clock switch is aborted. 2. if a valid clock switch has been initiated, the lock (osccon<5>) and the cf (osccon<3>) status bits are cleared. 3. 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 ). 4. the hardware waits for 10 clock cycles from the new clock source and then performs the clock switch. 5. the hardware clears the oswen bit to indicate a successful clock transit ion. in addition, the nosc<2:0> bit values are transferred to the cosc<2:0> status bits. 6. the old clock source is turned off at this time, with the exception of lprc (if wdt or fscm is enabled). 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 among the different primary submodes without reprogramming the device. 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 direc- tion. in these instances, the application must switch to frc mode as a transition clock source between the two pll modes. 3: refer to section 42. ?oscillator (part iv)? (ds70307) in the ?dspic33f/ pic24h family reference manual? for details. ? 2011-2012 microchip technology inc. ds75018c-page 135 dspic33fj06gs001/101a/102a/202a and dspic33fj09gs302 8.6 fail-safe clock monitor (fscm) 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 tr ap 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 c ontrolled shutdown. the trap can be treated as a warm reset by simply loading the reset address into the osci llator 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. 8.7 pseudo-random generator the pseudo-random generator is implemented with a 15-bit linear feedback shift register (lfsr), which is a shift register with a few exclusive or gates. the shift register is clocked by the pwm clock and is a read-only register. the purpose of this feature is to provide the ability to randomly change the period or the active portion of the pwm. a firmware routine can be used to read ?n? random bits from the lfsr register and combine them, by either summing or performing another logical operation with the pwm period of the duty cycle registers. the result will be a pwm signal whose nominal period (or duty cycle) is the desired one, but whose effective value changes randomly. this capability will help in reducing the emi/emc emissions by spreading the power over a wider frequency range. figure 8-3 provides a block diagram of the lfsr. figure 8-3: lfsr block diagram all zero detect 15 d q0 clk q d q1 clk q d q2 clk q d q3 clk q d q4 clk q d q5 clk q d q6 clk q d q7 clk q d q8 clk q d q9 clk q d q10 clk q d q11 clk q d q12 clk q d q13 clk q d q14 clk q lfsr dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 136 ?

clock frequency ? instruction-based sleep and idle modes ? software controlled doze mode ? selective peripheral control in software 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. 9.1 clock frequency and clock switching these devices allow a wide range of clock frequencies to be selected under applic ation control. if the system clock configuration is not locked, users can choose low-power or high-precision oscillators by simply changing the nosc<2:0> 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 8.0 ?oscillator configuration? . 9.2 instruction-based power-saving modes the 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 peri pheral modules to continue operation. the assembler syntax of the pwrsav instruction is shown in example 9-1 . 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. 9.2.1 sleep mode the following occur in sleep mode: ? 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 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. this includes items, such as the input change notification (icn) on the i/o ports or peripherals that use an external clock input. ? any peripheral that r equires the system clock source for its operation is disabled. the device will wake-up from sleep mode on any of these events: ? any interrupt source that is individually enabled ? any form of device reset ? a wdt time-out on wake-up from sleep mode, the processor restarts with the same clock source th at was active when sleep mode was entered. example 9-1: pwrsav instruction syntax note 1: this data sheet summ arizes the features of the dspic33fj 06gs001/101a/102a/ 202a and dspic33fj09gs302 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 9. ?watchdog timer (wdt) and power-saving modes?

2011-2012 microchip technology inc. 9.2.2 idle mode the following occur in idle mode: ? the cpu stops executing instructions. ? the wdt is automatically cleared. ? the system clock sour ce remains active. by default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see section 9.4 ?peripheral module disable? ). ? if the wdt or fscm is enabled, the lprc also remains active. the device will wake-up from idle mode on any of these events: ? any interrupt that is individually enabled ? any device reset ? a wdt time-out on wake-up from idle mode, the clock is reapplied to the cpu and instruction execution will begin (2-4 clock cycles later), starting with the instruction following the pwrsav instruction, or the first instruction in the isr. 9.2.3 interrupts coincident with power save instructions 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. 9.3 doze mode the preferred strategies for reducing power consumption are changing clock speed and invoking one of the power-saving modes. in some circumstances, this may not be practical. for example, it may be necessary for an application to maintain uninterrupted synchronous co mmunication, even while it is doing nothing else. reducing system clock speed can introduce communication errors, while using a power-saving mode can 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 th e 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. 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. programs can use doze mode to selectively reduce power consumption in event-driven applications. this allows clock-sensitive func tions, such as synchronous communications, to continue without interruption while the cpu idles, waiting for something to invoke an interrupt routine. an automatic return to full-speed cpu operation on interrupts can be enabled by setting the roi bit (clkdiv<15>). by default, interrupt events have no effect on doze mode operation. 9.4 peripheral module disable 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 disabl ed using 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 enabled only if both the associated bit in the pmd register is cleared and the peripheral is supported by the specific dspic ? 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 one instruction cycle. simila rly, if a pmd bit is cleared, the corresponding module is enabled after a delay of one instruction cycle (assuming the m odule control regis- ters are already configured to enable module operation). ?

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 t he 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 pin will read as zeros. when a pin is shared wit h another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other compet ing source of outputs. note 1: this data sheet summ arizes the features of the dspic33fj 06gs001/101a/102a/ 202a and dspic33fj09gs302 family of devices. 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?

pin diagrams ? section for the available pins and their functionality. 10.3 configuring analog port pins the adpcfg and tris regist ers control the operation of the analog-to-digital port pins. the port pins that are to function as analog inputs must have their corre- sponding tris bit set (input). if the tris bit is cleared (output), the digi tal output level (v oh or v ol ) will be converted. the adpcfg register has a default value of 0x0000; therefore, all pins that s hare anx functions are analog (not digital) by default. when the port register is read, 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, defined as a digital input (including the anx pins), can cause the input buffer to consume current that exceeds the device specifications. 10.4 i/o port write/read timing one instruction cycle is requ ired between a port direction change or port write operation and a read operation of the same port. typically, this instruction would be a nop . an example is shown in example 10-1 . 10.5 input change notification the input change notification function of the i/o ports allows devices to generate interrupt requests to the processor in response to a change-of-state (cos) on selected input pins. this feature can detect input change-of-states (cos), even in sleep mode when the clocks are disabled. de pending on the device pin count, up to 16 external signals (cnx pin) can be selected (enabled) for generating an interrupt request on a change-of-state. four control registers ar e associated with the cn module. the cnen1 register contains the interrupt enable control bits for each of the cn input pins. setting any of these bits enables a cn interrupt for the corresponding pin. each cn pin also has a weak pull-up connected to it. the pull-ups act as a current source connected to the pin and eliminate the need for external resistors when the push button or keypad devices are connected. the pull-ups are enabled separately, using the cnpu1 reg- ister, which contains the control bits for each of the cn pins. setting any of the control bits enables the weak pull-ups for the corresponding pins. example 10-1: port write/read example note: pull-ups on change notification pins should always be disabled when the port pin is configured as a digital output. mov 0xff00, w0 ; configure portb<15:8> as inputs mov w0, trisbb ; and portb<7:0> as outputs nop ; delay 1 cycle btss portb, #13 ; next instruction dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 148 ? 2011-2012 microchip technology inc. 10.6 peripheral pin select (pps) peripheral pin select configuration enables peripheral set selection and placement on a wide range of i/o pins. by increasing the pinout options available on a particular device, programmers can better tailor the microcontroller to their entire application, rather than trimming the application to fit the device. the peripheral pin select co nfiguration feature operates over a fixed subset of digi tal i/o pins. programmers can independently map the inpu t and/or output of most digital peripherals to any one of these i/o pins. peripheral pin select is performed in software and gen- erally does not require the device to be reprogrammed. hardware safeguards are included that prevent acciden- tal or spurious changes to the peripheral mapping once it has been established. 10.6.1 available pins the peripheral pin select fe ature is used with a range of up to 16 pins. the number of available pins depends on the particular device and its pin count. pins that support the peripheral pin select feature include the designation, ?rpn?, in their full pin designation, where ?rp? designates a remappable peripheral and ?n? is the remappable pin number. 10.6.2 controlling peripheral pin select peripheral pin select feat ures are controlled through two sets of special function registers: one to map peripheral inputs and one to map outputs. because they are separately controlled, a particular peripheral?s input and output (if the peripheral has both) can be placed on any selectable function pin without constraint. the association of a peripheral to a peripheral select- able pin is handled in two different ways, depending on whether an input or output is being mapped. 10.6.2.1 input mapping the inputs of the peripheral pin select options are mapped on the basis of the peripheral. a control register associated with a peripheral dictates the pin it will be mapped to. the rpinrx regist ers are used to configure peripheral input mapping (see register 10-1 through register 10-15 ). each register contains sets of 6-bit fields, with each set associated with one of the remappable peripherals. programming a given peripheral?s bit field with an appropriate 6-bit value maps the rpn pin with that value to that peripheral. for any given device, the valid range of values for any bit field corresponds to the maximum number of peripheral pin selections supported by the device. figure 10-2 illustrates the remappable pin selection for the u1rx input. figure 10-2: remappable mux input for u1rx note: for input mapping only, the peripheral pin select (pps) functio nality does not have priority over the trisx settings. there- fore, when configuring the rpx pin for input, the corresponding bit in the trisx register must also be configured for input (i.e., set to ? 1 ?). rp0 rp1 rp2 rp15 0 15 1 2 u1rx input u1rxr<5:0> to peripheral ? 2011-2012 microchip technology inc. ds75018c-page 149 dspic33fj06gs001/101a/102a/202a and dspic33fj09gs302 table 10-1: selectable input sour ces (maps input to function) input name function name register configuration bits external interrupt 1 int1 rpinr0 int1r<5:0> external interrupt 2 int2 rpinr1 int2r<5:0> timer1 external clock t1ck rpinr2 t1ckr<5:0> timer2 external clock t2ck rpinr3 t2ckr<5:0> input capture 1 ic1 rpinr7 ic1r<5:0> output compare fault a ocfa rpinr11 ocfar<5:0> uart1 receive u1rx rpinr18 u1rxr<5:0> uart1 clear-to-send u1cts rpinr18 u1ctsr<5:0> spi data input 1 sdi1 rpinr20 sdi1r<5:0> spi clock input 1 sck1 rpinr20 sck1r<5:0> spi slave select input 1 ss1 rpinr21 ss1r<5:0> pwm fault input flt1 rpinr29 flt1r<5:0> pwm fault input flt2 rpinr30 flt2r<5:0> pwm fault input flt3 rpinr30 flt3r<5:0> pwm fault input flt4 rpinr31 flt4r<5:0> pwm fault input flt5 rpinr31 flt5r<5:0> pwm fault input flt6 rpinr32 flt6r<5:0> pwm fault input flt7 rpinr32 flt7r<5:0> pwm fault input flt8 rpinr33 flt8r<5:0> external synchronization signal to pwm ma ster time base synci1 rpinr33 synci1r<5:0> external synchronization signal to pwm ma ster time base synci2 rpinr34 synci2r<5:0> dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 150 ? 2011-2012 microchip technology inc. 10.6.2.2 output mapping in contrast to inputs, the outputs of the peripheral pin select options are mapped on the basis of the pin. in this case, a control register associated with a particular pin dictates the peripheral output to be mapped. the rporx registers are used to control output mapping. like the rpinrx registers, each register contains sets of 6-bit fields, with each set associated with one rpn pin (see register 10-16 through register 10-25 ). the value of the bit field corresponds to one of the peripherals and that peripher al?s output is mapped to the pin (see table 10-2 and figure 10-3 ). the list of peripherals for output mapping also includes a null value of ? 00000 ? because of the mapping technique. this permits any given pin to remain unconnected from the outpu t of any of the pin selectable peripherals. figure 10-3: multiplexing of remappable output for rpn table 10-2: output selection for remappable pin (rpn) 0 45 3 rporn<5:0> default u1tx output enable u1rts output enable 4 pwm4l output enable 18 oc1 output enable 0 45 3 default u1tx output u1rts output 4 pwm4l output 18 oc1 output output enable output data rpn function rporn<5:0> output name null 000000 rpn tied to default port pin u1tx 000011 rpn tied to uart1 transmit u1rts 000100 rpn tied to uart1 ready-to-send sdo1 000111 rpn tied to spi1 data output sck1 001000 rpn tied to spi1 clock output ss1 001001 rpn tied to spi1 slave select output oc1 010010 rpn tied to output compare 1 synco1 100101 rpn tied to external device synchroni zation signal via pwm master time base refclko 100110 refclk output signal acmp1 100111 rpn tied to analog comparator 1 output acmp2 101000 rpn tied to analog comparator 2 output pwm4h 101100 rpn tied to pwm output pins a ssociated with pw m generator 4 pwm4l 101101 rpn tied to pwm output pins a ssociated with pw m generator 4 ?

control register lock sequence ? continuous state monitoring ? configuration bit pin select lock 10.6.3.1 control register lock under normal operation, writ es to the rpinrx and rporx registers are not al lowed. attempted writes appear to execute normally, but the contents of the registers remain unchanged. to change these registers, they must be unlocked in hardware. the register lock is contro lled by the iolock bit (osccon<6>). sett ing iolock prevents writes to the control registers; clearin g iolock allows writes. to set or clear iolock, a specific command sequence must be executed: 1. write 0x46 to osccon<7:0>. 2. write 0x57 to osccon<7:0>. 3. clear (or set) iolock as a single operation. unlike the similar sequence with the oscillator?s lock bit, iolock remains in one state until changed. this allows all of the peripheral pin selects to be configured with a single unlock sequence, followed by an update to all control registers, then locked with a second lock sequence. 10.6.3.2 continuous state monitoring in addition to being protect ed from direct writes, the contents of the rpinrx and rporx registers are constantly monitored in hardware by shadow registers. if an unexpected change in any of the registers occurs (such as cell disturbances caused by esd or other external events), a configuration mismatch reset will be triggered. 10.6.3.3 configuration bit pin select lock as an additional level of safety, the device can be configured to prevent more than one write session to the rpinrx and rporx r egisters. the iol1way (fosc<5>) configuration bi t blocks the iolock bit from being cleared, after it has been set once. if iolock remains set, the r egister unlock procedure will not execute and the peripheral pin select control registers cannot be written to. the only way to clear the bit and re-enable peripheral remapping is to perform a device reset. in the default (unprogramm ed) state, iol1way is set, restricting users to one write session. programming iol1way allows user applications unlimited access (with the proper use of the unlock sequence) to the peripheral pin select registers. note: mplab ? c30 provides built-in c language functions for unlocking the osccon register: __builtin_write_oscconl(value) __builtin_write_oscconh(value) see the mplab c30 help files for more information. dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 152 ? 2011-2012 microchip technology inc. 10.7 i/o helpful tips 1. in some cases, certain pins, as defined in table 25-9 under ?injection current?, have internal protection diodes to v dd and v ss . the term, ?injection current?, is al so referred to as ?clamp current?. on designated pins, with sufficient exter- nal current limiting precautions by the user, i/o pin input voltages are allowed to be greater or less than the data sheet absolute maximum ratings with respect to the v ss and v dd supplies. note that when the user application forward biases either of the high or low side internal input clamp diodes, that the resulting current being injected into the device that is clamped internally by the v dd and v ss power rails, may affect the adc accuracy by four to six counts. 2. i/o pins that are shared with any analog input pin (i.e., anx) are always analog pins by default after any reset. consequently, any pin(s) configured as an analog input pin, automatically disables the dig- ital input pin buffer. as such, any attempt to read a digital input pin will always return a ? 0 ?, regardless of the digital logic level on the pin if the analog pin is configured. to use a pin as a digital i/o pin on a shared anx pin, the user application needs to con- figure the analog pin register in the adc module (i.e., adpcfg) by setting the appropriate bit that corresponds to that i/o port pin to a ? 1 ?. on devices with more than one adc, both analog pin configu- rations for both adc modules must be configured as a digital i/o pin for that pin to function as a digital i/o pin. 3. most i/o pins have multiple functions. referring to the device pin diagrams in the data sheet, the priorities of the functions allocated to any pins are indicated by reading the pin name from left-to-right. the left most function name takes precedence over any function to its right in the naming convention; for example: an2/cmp1c/cmp2a/ra2. this indi- cates that an2 is the highest priority in this example and will supersede all other functions to its right in the list. those other functions to its right, even if enabled, would not work as long as any other func- tion to its left was enabled. this rule applies to all of the functions listed for a given pin. 4. each cn pin has a configurable internal weak pull-up resistor. the pull-ups act as a current source connected to the pin and eliminates the need for external resistors in certain applica- tions. the internal pull-up is to ~(v dd ? 0.8), not v dd . this is still above the minimum v ih of cmos and ttl devices. 5. when driving leds directly, the i/o pin can source or sink more current than what is specified in the v oh /i oh and v ol /i ol dc char- acteristics specificati on. the respective i oh and i ol current rating only applies to maintaining the corresponding output at or above the v oh , and at or below the v ol levels. however, for leds, unlike digital inputs of an externally connected device, they are not governed by the same min- imum v ih /v il levels. an i/o pin output can safely sink or source any current less than that listed in the ?absolute maximum ratings(1)? in section 25.0, electric al characteristics of this data sheet. for example: v oh = 2.4v @ i ol = -6 ma and v dd = 3.3v the maximum output current sourced by any 4x i/o pin = 15 ma. led source current <15 ma is technically permitted. refer to the v oh /i oh graphs in section 26.0 ?dc and ac device characteristics graphs?

2011-2012 microchip technology inc. 15.2 feature description the pwm module is designed for applications that require: ? high-resolution at high pwm frequencies ? the ability to drive standard, edge-aligned, center-aligned complementary mode, and push-pull mode outputs ? the ability to create multiphase pwm outputs for center-aligned mode, t he duty cycle, period, phase and dead-time resolutions will be 8.32 ns. two common, medium power converter topologies are push-pull and half-bridge. these designs require the pwm output signal to be s witched between alternate pins, as provided by the push-pull pwm mode. a phase-shifted pwm describes the situation where each pwm generator provides outputs, but the phase relationship between the generator outputs is specifiable and changeable. a multiphase pwm is oft en used to improve dc/dc converter load transient response, and reduce the size of output filter capacitors and inductors. multiple dc/ dc converters are often operated in parallel, but phase-shifted in time. a single pwm output, operating at 250 khz, has a period of 4 ? s, but an array of four pwm channels staggered by 1 ? s each, yields an effective switching frequen cy of 1 mhz. multiphase pwm applications typically use a fixed-phase relationship. a variable phase pwm is useful in zero voltage transition (zvt) power converters. here, the pwm duty cycle is always 50%, and the power flow is controlled by varying the relative phase-shift between the two pwm generators. ?

spi and siop. 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, spix buf. a control register, spixcon, configures the m odule. additionally, a status register, spixstat, indi cates status conditions. the serial interface consists of 4 pins: ? sdix (serial data input) ? sdox (serial data output) ? sckx (shift clock input or output) ? ssx (active-low slave select) in master mode operation, sckx is a clock output; in slave mode, it is a clock input. figure 16-1: spi module block diagram note 1: this data sheet summarizes the features of the dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 family of devices. it is not intended to be a compre- hensive reference source. to complement the information in this data sheet, refer to section 18. ?serial peripheral interface (spi)?

adcpc3: adc convert pair control register 3(1) the adcon register contro ls the operation of the adc module. the adstat register displays the status of the conversion processes. the adpcfg register configures the port pins as analog inputs or as digital i/os. the adcpcx registers control the triggering of the adc conversions. see register 19-1 through register 19-7 for detailed bit configurations. note: a unique feature of the adc module is its ability to sample inputs in an asynchronous manner. individual sample-and-hold circuits can be triggered independently of each other. register 19-1: adcon: adc control register r/w-0 u-0 r/w-0 r/w-0 u-0 r/w-0 u-0 r/w-0 adon ?adsidlslowclk ( 1 ) ?gswtrg ?form (1) bit 15 bit 8 r/w-0 r/w-0 r/w-0 r/w-0 u-0 r/w-0 r/w-1 r/w-1 eie ( 1 ) order ( 1 ) seqsamp ( 1 ) asyncsamp ( 1 ) ?

eight selectable comparator inputs ? up to two analog comparators ? 10-bit dac for each analog comparator ? programmable output polarity ? interrupt generation capability ? dacout pin to provide dac output ? dacout amplifier (1x, 1.8x) ? selectable hysteresis ? dac has three ranges of operation: -av dd /2 - internal reference (intref) - external reference (extref) ? adc sample and convert trigger capability ? disable capability reduces power consumption ? functional support for pwm module: - pwm duty cycle control - pwm period control - pwm fault detect 20.2 module description figure 20-1 shows a functional block diagram of one analog comparator from the high-speed analog comparator module. the analog comparator provides high-speed operation with a ty pical delay of 20 ns. the comparator has a typical offset voltage of 5 mv. the negative input of the compar ator is always connected to the dac circuit. the positive input of the comparator is connected to an analog multiplexer that selects the desired source pin. the analog comparator input pins are typically shared with pins used by the analog-to-digital converter (adc) module. both the comparator and the adc can use the same pins at the same time. this capability enables a user to measure an input voltage with the adc and detect voltage transients with the comparator. figure 20-1: high-speed analog co mparator module block diagram note 1: this data sheet summarizes the features of the dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 families of devices. it is not intended to be a comprehensive reference source. to complement the inform ation in this data sheet, refer to section 45. ?high-speed analog comparator?

2011-2012 microchip technology inc. 20.3 module applications this module provides a means for the smps dspic dsc devices to monitor voltage and currents in a power conversion application. the ability to detect transient conditions and stimulate the dspic dsc processor and/or periphera ls, without requiring the processor and adc to constantly monitor voltages or currents, frees the dspic dsc to perform other tasks. the comparator module has a high-speed comparator, an associated 10-bit dac and a dac output amplifier that provide a programmable reference voltage to the inverting input of the comp arator. the polarity of the comparator output is user -programmable. the output of the module can be used in the following modes: ? generate an interrupt ? trigger an adc sample and convert process ? truncate the pwm signal (current limit) ? truncate the pwm period (current minimum) ? disable the pwm outputs (fault latch) the output of the comparat or module may be used in multiple modes at the same time, such as: 1) generate an interrupt, 2) have the adc take a sample and con- vert it, and 3) truncate t he pwm output in response to a voltage being detected beyond its expected value. the comparator module can also be used to wake-up the system from sleep or idle mode when the analog input voltage exceeds the programmed threshold voltage. 20.4 dac the range of the dac is controlled via an analog multiplexer that selects either av dd /2, an internal reference source, intref, or an external reference source, extref. the full range of the dac (av dd /2) will typically be used when the chosen input source pin is shared with the adc. the reduced range option (intref) will likely be used when monitoring current levels using a current sense resistor. usually, the measured voltages in such applications are small (<1.25v); therefore, the option of using a reduced reference range for the comparator extends the available dac resolution in these applications. the use of an external reference enables the user to connect to a reference that better suits their application. dacout, shown in figure 20-1 , can only be associated with a single comparator at a given time. 20.5 dac buffer gain the output of the dac is buffered/amplified via the dac buffer. the block functions as a 1x gain amplifier or as a 1.8x gain amplifier. the gain selection is con- trolled via the hgain bit in the cmpconx register. using the 1.8x gain option will raise the reference voltage to the analog comparator to a maximum of 2.8v. using a higher reference voltage for the analog comparator can improve the signal-to-noise ratio in an application. 20.6 comparator input range the comparator has an input voltage range from -0.2v to av dd + 0.2v, making it a rail-to-rail input. 20.7 digital logic the cmpconx register (see register 20-1 ) provides the control logic that conf igures the high-speed analog comparator module. the digital logic provides a pulse stretcher. the analog comparator can respond to very fast transient signals. af ter the comparator output is given the desired polarity, the signal is passed to this pulse stretching circuit. the pulse stretching circuit has an asynchronous set function and a delay circuit that insure the minimum pulse width is three system clock cycles wide so that the atta ched circuitry can properly respond. the stretch circuit is followed by a digital filter. the digital filter is enabled via the fltren bit in the cmpconx register. the digital filter operates with the clock specified via the fc lksel bit in the cmpconx register. the comparator signal must be stable in a high or low state for at least three of the selected clock cycles for it to pass thro ugh the digital filter. during sleep mode, the clock signal inputs to the module are disabled. however, the module?s analog components may continue to function in a reduced power manner to allow the user to wake-up the device when a signal is applied to a comparator input. in sleep mode, the clocks are stopped; however, the analog comparator signal has an asynchronous con- nection across the filter that allows interrupts to be generated regardless of the stopped clocks. the comparator can be disabled while in idle mode if the cmpsidl bit is set. if a device has multiple compar- ators, and any cmpsidl bit is set, the entire group of comparators will be disabled while in idle mode. the advantage is reduced power consumption. moreover, this behavior reduces complexity in the design of the clock control logic for this module. note: it should be ensured in software that multiple dacoe bits are not set. the output on the dacout pin will be indeter- minate if multiple comparators enable the dac output. ?

1.5) volts. an external reference voltage input should not exceed this value or the reference dac output will become indeterminate. 20.11 analog comparator registers the high-speed analog comparator module is controlled by the following registers: ?

. on a por , it takes approximately 20 ? s for the on-chip voltage regulator to generate an output voltage. during this time, designated as t startup , code execution is disabled. t startup is applied every time the device resumes operation after any power-down. figure 22-1: connections for the on-chip voltage regulator ( 1 , 2 , 3 ) 22.3 brown-out reset (bor) the brown-out reset (bor) module is based on an internal voltage reference circuit. 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 (for example, 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 generates a reset pulse which resets the device. the bor selects the clock source, based on the device configuration bit values (fnosc<2:0> and poscmd<1:0>). if an oscillator mode is selected, the bor activates the oscillator start-up timer (o st). the system clock is held until the ost expires. if the pll is used, the clock is held until the lock bit (osccon<5>) is ? 1 ?. concurrently, the pwrt time -out (tpwrt) is applied before the internal reset is released. if tpwrt = 0 and a crystal oscillator is being used, then a nominal delay of, t fscm = 100 , is applied. the total delay in this case is t fscm . the bor status bit (rcon<1>) is set to indicate that a bor has occurred. the bor circuit continues to operate while in sleep or idle modes and resets the device should v dd fall below the bor threshold voltage. note: it is important for the low-esr capacitor to be placed as close as possible to the v cap pin. note 1: these are typical operating voltages. refer to table 25-13 located in section 25.1 ?dc characteristics?

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 22.4.2 sleep and idle modes 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 dev ice and code execution will continue from where the pwrsav instruction was executed. the correspondi ng sleep bit (rcon<3>) or idle bit (rcon<2>) will need to be cleared in software after the device wakes up. 22.4.3 enabling wdt the wdt is enabled or disabled by the fwdten configuration bit in the fw dt configuration register (fwdt<7>). 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 application to enable the wdt for critical code segments and disable the wdt during non-critical segments for maximum power savings. 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. figure 22-2: wdt block diagram note: the clrwdt and pwrsav instructions clear the prescaler and postscaler counts when executed. 0 1 wdtpre wdtpost<3:0> watchdog timer sleep/idle wdt wdt window select wdt clrwdt instruction swdten fwdten lprc clock wake-up reset all device resets transition to new clock source exit sleep or idle mode pwrsav instruction clrwdt instruction prescaler (divide-by-n1) rs postscaler (divide-by-n2) rs dspic33fj06gs001/101a/102a/ 202a and dspic33fj09gs302 ds75018c-page 258 ? 2011-2012 microchip technology inc. 22.5 jtag interface a jtag interface is implemented, which supports boundary scan device testing, as well as in-circuit programming. detailed information on this interface will be provided in future revisions of this document. 22.6 in-circuit serial programming the dspic33fj06gs001/101a/102a/202a and dspic33fj09gs302 family of digital signal controllers can be serially programmed while in the end application circuit. this is done with two lines for clock and data, and three other lines for power, ground and the programming sequence. serial programming allows customers to manufacture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. serial programming also allows the most recent firmware or a custom firmware to be programmed. refer to the ?dspic33f/pic24h flash programming specification? (ds70152) for details about in-circuit serial programming (icsp?). any of the three pairs of programming clock/data pins can be used: ? pgec1 and pged1 ? pgec2 and pged2 ? pgec3 and pged3 22.7 in-circuit debugger the dspic33fj06gs001/ 101a/102a/202a and dspic33fj09gs302 devices provide simple debug- ging functionality through the pgecx (emulation/ debug clock) and pgedx (emulation/debug data) pin functions. any of the three pairs of debugging clock/data pins can be used: ? pgec1 and pged1 ? pgec2 and pged2 ? pgec3 and pged3 to use the in-circuit debug ger function of the device, the design must implement icsp connections to mclr , v dd , v ss 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. ? 2011-2012 microchip technology inc. ds75018c-page 259 dspic33fj06gs001/101a/102a/202a and dspic33fj09gs302 23.0 instruction set summary the instruction set for this family of dspic33f devices is identical to the instruction set for dspic30f devices. 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 oper ands, 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 23-1 shows the general symbols used in describing the instructions. the dspic33f instruct ion set summary in ta b l e 2 3 - 2 lists all the instructions, along with the status flags affected by each instruction. most word or byte-oriente d 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 wit hout 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 c ould be either the file register, ?f?, or the w0 register, which is denoted as ?wreg? most bit-oriented instructions (including simple rotate/ shift instructions) have two operands: ? 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 can use some of the following operands: ? a literal value to be loaded into a w register or file register (specified by ?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 can 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 can 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 spec ified by a w register, ?wn?, or a literal value the control instructions can use some of the following operands: ? a program memory address ? the mode of the table read and table write instructions note: this data sheet summ arizes the features of the dspic33fj 06gs001/101a/102a/ 202a and dspic33fj09gs302 devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?dspic33f/pic24h family reference manual?

0 ?s. if this second word is executed as an instruction (by itself), it will execute as a nop . the double-word instructions execute in two instruction cycles. 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. note: for more details on the instruction set, refer to the ?16-bit mcu and dsc programmer?s reference manual?
