(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? ) additionally, the following pins may be required: ?v ref +/v ref - pins used when external voltage reference for adc module is implemented 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: this data sheet summarizes the features of the pic24hj xxxgpx06/x08/x10 family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?pic24h family reference manual? , which is available from the microchip website (www.microchip.com). note: the av dd and av ss pins must be connected independent of the adc voltage reference source.

? 2009 microchip technology inc. ds70175h-page 17 pic24hjxxxgpx06/x08/x10 2.5 icsp pins the pgecx and pgedx pins are used for in-circuit serial programming? (icsp?) and debugging pur- poses. 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 t he ac/dc characteristics and timing requirements information in the respective device flash programming spec ification for information on capacitive loading limits and pin input voltage high (v ih ) and input low (v il ) requirements. ensure that the ?communication channel select? (i.e., pgecx/pgedx pins) programmed into the device matches the physical con nections for the icsp to mplab ? icd 2, mplab icd 3, or mplab real ice?. for more information on icd 2, icd 3 and real ice connection requirements, refer to the following documents that are availabl e on the microchip website. ? ?mplab ? icd 2 in-circuit debugger user?s guide? ds51331 ? ?using mplab ? icd 2?

(poster) ds51749 2.6 external oscillator pins many mcus have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to section 9.0 ?oscillator configuration? for details). the oscillator circuit should be placed on the same side of the board as the device. also, place the oscillator circuit close to 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

? 2009 microchip technology inc. ds70175h-page 19 pic24hjxxxgpx06/x08/x10 3.0 cpu the pic24hjxxxgpx06/x08/ x10 cpu module has a 16-bit (data) modified harvard architecture with an enhanced instruction set and addressing modes. the cpu has a 24-bit instruction word with a variable length opcode field. the program counter (pc) is 23 bits wide and addresses up to 4m x 24 bits of user program memory space. the actual amount of program memory implemented varies by device. a single-cycle instruction prefetch mechanism is used to help maintain throughput and provides predictable exec ution. all instructions execute in a single cycl e, with the exception of instructions that change the program flow, the double word move ( mov.d ) instruction and the table instructions. overhead-free, single-cycle pr ogram loop constructs are supported using the repeat instruction, which is interruptible at any point. the pic24hjxxxgpx06/x08/x10 devices have sixteen, 16-bit working regi sters in the programmer?s model. each of the working registers can serve as a data, address or address offset register. the 16th working register (w15) operates as a software stack pointer (sp) for interrupts and calls. the pic24hjxxxgpx06/x08/ x10 instruction set includes many addressing modes and is designed for optimum c compiler efficiency. for most instructions, the pic24hjxxxgpx06/x0 8/x10 is capable of executing a data (or program data) memory read, a working register (data) read , a data memory write and a program (instruction) me mory read per instruction cycle. as a result, three pa rameter instructions can be supported, allowing a + b = c operations to be executed in a single cycle. a block diagram of the cpu is shown in figure 3-1, and the programmer?s model for the pic24hjxxxgpx06/x0 8/x10 is shown in figure 3-2. 3.1 data addressing overview the data space can be linearly addressed as 32k words or 64 kbytes using an addr ess generation unit (agu). the upper 32 kbytes of the data space memory map can optionally be mapped into program space at any 16k pro- gram word boundary defined by the 8-bit program space visibility page (psvpag) register. the program to data space mapping feature lets any instruction access pro- gram space as if it were data space. the data space also includes 2 kbytes of dma ram, which is primarily used for dma data transfers, but may be used as general purpose ram. 3.2 special mcu features the pic24hjxxxgpx06/x08/x1 0 features a 17-bit by 17-bit, single-cycle multip lier. the multiplier can perform signed, unsigned and mixed-sign multiplication. using a 17-bit by 17-bit multiplier for 16-bit by 16-bit multiplication makes mixed-sign multiplication possible. the pic24hjxxxgpx06/x08/x10 supports 16/16 and 32/16 integer divide operations. all divide instructions are iterative operations. they must be executed within a repeat loop, resulting in a total execution time of 19 instruction cycles. the di vide operat ion can be interrupted during any of those 19 cycles without loss of data. a multi-bit data shifter is used to perform up to a 16-bit, left or right shift in a single cycle. note: this data sheet summarizes the features of the pic24hjxxxg px06/x08/x10 fam- ily of devices. however, it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?pic24h family refer- ence manual? , section 2. ?cpu?

(ds70157) for information on the sr bits affected by each instruction. the pic24hjxxxgpx06/x08/ x10 cpu incorporates hardware support for both multiplication and division. this includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 3.4.1 multiplier using the high-speed 17-bit x 17-bit multiplier, the alu supports unsigned, signed or mixed-sign operation in several multiplication modes: 1. 16-bit x 16-bit signed 2. 16-bit x 16-bit unsigned 3. 16-bit signed x 5-bit (literal) unsigned 4. 16-bit unsigned x 16-bit unsigned 5. 16-bit unsigned x 5-bit (literal) unsigned 6. 16-bit unsigned x 16-bit signed 7. 8-bit unsigned x 8-bit unsigned 3.4.2 divider the divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: 1. 32-bit signed/16-bit signed divide 2. 32-bit unsigned/16-bit unsigned divide 3. 16-bit signed/16-bit signed divide 4. 16-bit unsigned/16-bit unsigned divide the quotient for all divide instructions ends up in w0 and the remainder in w1. sixteen-bit signed and unsigned div instructions can s pecify 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-b it/16-bit instructions take the same number of cycles to execute. 3.4.3 multi-bit data shifter the multi-bit data shifter is capable of performing up to 16-bit arithmetic or logic righ t shifts, or up to 16-bit left shifts in a single cycle. th e source can be either a working register or a memory location. 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.

? 2009 microchip technology inc. ds70175h-page 27 pic24hjxxxgpx06/x08/x10 4.2 data address space the pic24hjxxxgpx06/x08/x10 cpu has a sepa- rate 16-bit wide data memory space. the data space is accessed using separate address generation units (agus) for read and write operations. data memory maps of devices with different ram sizes are shown in figure 4-3 and figure 4-4. all effective addresses (eas) in the data memory space are 16 bits wide and point to bytes within the data space. this arrangement gives a data space address range of 64 kbytes or 32k words. the lower half of the data memory space (that is, when ea<15> = 0 ) is used for implemented memory addresses, while the upper half (ea<15> = 1 ) is reserved for the program space visibility area (see section 4.4.3 ?reading data from program memory using program space visibility? ). pic24hjxxxgpx06/x08/x10 devices implement up to 16 kbytes 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 address- able, 16-bit wide blocks. data is aligned in data memory and registers as 16-bit words, but all data space eas resolve to bytes. the least significant bytes of each word have even addresses, while the most significant bytes have odd addresses. 4.2.2 data memory organization and alignment to maintain backward compatibility with pic ? mcu devices and improve data space memory usage efficiency, the pic24hjxxxgpx06/x08/x10 instruc- tion set supports both word and byte operations. as a consequence of byte accessibi lity, all effective address calculations are internally scaled to step through word- aligned memory. for example, the core recognizes that post-modified register indirect addressing mode [ws++] will result in a value of ws + 1 for byte operations and ws + 2 for word operations. data byte reads will read the complete word that contains the byte, using the least significant bit (lsb) of any ea to determine which byte to select. the selected byte is placed onto the least significant byte (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 which 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 opera- tions, or translating from 8-bit mcu code. if a mis- aligned 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 it occurred on a write, the instruction will be executed but the write does not occur. in either case, a trap is then executed, allow- ing the system and/or user to examine the machine state prior to execution of the address fault. all byte loads into any w register are loaded into the least significant byte. th e most significant byte (msb) is not modified. a sign-extend instruction ( se ) is provided to allow users to translate 8-bit signed data to 16-bit signed values. alternatively, for 16-bit unsigned data, users can clear the most significant byte 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 pic24hjxxxgpx06/x08/x10 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 ?. a complete listing of implemented sfrs, including their addresses, is shown in table 4-1 through table 4-33. 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. please refer to the corresponding device tables and pinout diagrams for device-specific information.

? 2009 microchip technology inc. ds70175h-page 51 pic24hjxxxgpx06/x08/x10 table 4-34: fundamental addressing modes supported 4.3.3 move instructions move instructions provide a greater degree of address- ing flexibility than other instructions. in addition to the addressing modes supported by most mcu instruc- tions, move instructions also support register indirect with register offset addres sing mode, also referred to as register indexed mode. in summary, the following addressing modes are supported by move instructions: ? register direct ? register indirect ? register indirect post-modified ? register indirect pre-modified ? register indirect with register offset (indexed) ? register indirect with literal offset ? 8-bit literal ? 16-bit literal 4.3.4 other instructions besides the various addressing modes outlined above, some instructions use literal constants of various sizes. for example, bra (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the disi instruction uses a 14-bit unsigned literal field. in some instructions, the source of an oper- and or result is implied by the opcode itself. certain operations, such as nop , do not have any operands. 4.4 interfacing program and data memory spaces the pic24hjxxxgpx06/x08/x1 0 architecture uses a 24-bit wide program space and a 16-bit wide data space. the architecture is also a modified harvard scheme, meaning that data can also be present in the program space. to use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. aside from normal execution, the pic24hjxxxgpx06/x08/x10 architecture provides two methods by which program space can be accessed during operation: ? using table instructions to access individual bytes or words anywhere in the program space ? remapping a portion of the program space into the data space (program space visibility) table instructions allow an application to read or write to small areas of the program memory. this capability makes the method ideal for accessing data tables that need to be updated from time to time. it also allows access to all bytes of the program word. the remap- ping method allows an application to access a large block of data on a read-only basis, which is ideal for look ups from a large table of static data. it can only access the least significant word of the program word. 4.4.1 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 ). 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 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 of fset 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 between 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.
pic24hjxxxgpx06/x08/x10 ds70175h-page 52 ? 2009 microchip technology inc. for remapping operations, the 8-bit program space visibility register (psvpag) is used to define a 16k word page in the program space. when the most significant bit of the ea is ? 1 ?, psvpag is concatenated with the lower 15 bits of t he ea to form a 23-bit program space address. unlike table operations, this limits remapping operations strictly to the user memory area. table 4-35 and figure 4-6 show how the program ea is created for table operations and remapping accesses from the data ea. here, p<23:0> refers to a program space word, whereas d<15:0> refers to a data space word. table 4-35: program sp ace 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 0xxx 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 ? 1 ? in this case, but is not used in calculating the program space address. bit 15 of the address is psvpag<0>.

(icsp?) programming capability 2. run-time self-programming (rtsp) icsp programming capability allows a pic24hjxxxgpx06/x08/x10 device to be serially programmed while in the end application circuit. this is simply done with two lines for programming clock and programming data (one of the alternate programming pin pairs: pgecx/pgedx, and three other lines for power (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 firm- ware to be programmed. rtsp is accomplished using tblrd (table read) and tblwt (table write) instructions. with rtsp, the user can write program memory data either in blocks or ?rows? of 64 instructions (192 bytes) at a time, or single instructions 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: this data sheet summarizes the features of the pic24hj xxxgpx06/x08/x10 family of devices. however, it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?pic24h family reference manual? , section 5. ?flash programming?

(ds70224), which is available from the microchip website (www.microchip.com). note: any unimplemented or unused vector locations in the ivt and aivt should be programmed with the address of a default interrupt handler routine that contains a reset instruction.

? 2009 microchip technology inc. ds70175h-page 111 pic24hjxxxgpx06/x08/x10 8.0 direct memory access (dma) direct memory access (dma) is a very efficient mechanism of copying data between peripheral sfrs (e.g., uart receive register, input capture 1 buffer), and buffers or variables stored in ram, with minimal cpu intervention. the dma controller can automatically copy entir e blocks of data without requiring the user software to read or write the peripheral special function registers (sfrs) every time a peripheral interrupt occurs. the dma controller uses a dedicated bus for data transfers and, therefore, does not steal cycles from the code execution flow of the cpu. to exploit the dma capability, the corresponding user buffers or variables must be located in dma ram. the pic24hjxxxgpx06/x0 8/x10 peripherals that can utilize dma are listed in table 8-1 along with their associated interrupt request (irq) numbers. table 8-1: peripherals with dma support the dma controller featur es eight identical data transfer channels. each channel has its own set of control and status registers. each dma channel can be configured to copy data either from buffers stored in dual port dma ram to peripheral sfrs, or from peripheral sfrs to buffers in dma ram. the dma controller supports the following features: ? word or byte sized data transfers. ? transfers from peripheral to dma ram or dma ram to peripheral. ? indirect addressing of dm a ram locations with or without automatic post-increment. ? peripheral indirect addressing ? in some periph- erals, the dma ram r ead/write addresses may be partially derived from the peripheral. ? one-shot block transfers ? terminating dma transfer after one block transfer. ? continuous block transfers ? reloading dma ram buffer start address after every block transfer is complete. ? ping-pong mode ? switching between two dma ram start addresses be tween successive block transfers, thereby filling two buffers alternately. ? automatic or manual initiation of block transfers ? each channel can select from 19 possible sources of data sources or destinations. for each dma channel, a dma interrupt request is generated when a block transfer is complete. alternatively, an interrupt can be generated when half of the block has been filled. note: this data sheet summarizes the features of the pic24hjxxxg px06/x08/x10 fam- ily of devices. however, it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?pic24h family refer- ence manual? , section 22. ?direct mem- ory access (dma)?

(refer to section 21.1 ?configuration bits? for further details.) the initial oscillator selection configuration bits, fnosc<2:0> (foscsel<2:0>), and the primary oscil- lator mode select configuration bits, poscmd<1:0> (fosc<1:0>), select the osc illator source that is used at a power-on reset. the frc primary oscillator is the default (unprogrammed) selection. the configuration bits allow users to choose between twelve different clock modes, shown in table 9-1. the output of the oscillator (or the output of the pll if a pll mode has been selected) 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 dev ice, and speeds up to 40 mhz are supported by th e pic24hjxxxgpx06/x08/ x10 architecture. instruction execution speed or device operating frequency, f cy , is given by: equation 9-1: device operating frequency 9.1.3 pll configuration the primary oscillator and internal frc oscillator can optionally use an on-chip pll to obtain higher speeds of operation. the pll prov ides a significant amount of flexibility in selecting the device operating speed. a block diagram of the pll is shown in figure 9-2. the output of the pr imary oscillator or frc, denoted as ?f in ?, is divided down by a pre scale factor (n1) of 2, 3, ... or 33 before being provided to the pll?s voltage controlled oscillator (vco). the input to the vco must be selected to be in the range of 0.8 mhz to 8 mhz. since the minimum prescale factor is 2, this implies that f in must be chosen to be in the range of 1.6 mhz to 16 mhz. the prescale factor ?n1? is selected using the pllpre<4:0> bits (clkdiv<4:0>). the pll feedback divisor, selected using the plldiv<8:0> bits (pllfbd<8:0>), provides a factor ?m?, by which the input to the vco is multiplied. this factor must be selected such that the resulting vco output frequency is in the range of 100 mhz to 200 mhz. the vco output is further divided by a postscale factor ?n2?. this factor is selected using the pllpost<1:0> bits (clkdiv<7:6>). ?n2? can be either 2, 4 or 8, and must be selected such that the pll output frequency (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 9-2: f osc calculation f cy f osc 2 ------------- = f osc f in m n 1 n 2 ? ------------------ - ?? ?? ? =

(refer to section 21.1 ?configuration bits? for further details.) if the fcksm1 configuration bit is unprogrammed (? 1 ?), the clock switching function and fail-safe clock monitor function are disabled. this is the default setting. the nosc control bits (osccon<10:8>) do not control the clock selecti on when clock switching is disabled. however, the cosc bits (osccon<14:12>) reflect the clock source selected by the fnosc configuration bits. the oswen control bit (osccon<0>) has no effect when clock switching is disabled. it is held at ? 0 ? at all times. 9.2.2 oscillator switching sequence at a minimum, performing a clock switch requires this basic sequence: 1. if desired, read the cosc bits (osccon<14:12>) 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 control bits (osccon<10:8>) 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 to initiate the oscillator switch. once the basic sequence is completed, the system clock hardware responds automatically as follows: 1. the clock switching hardware compares the cosc status bits with the new value of the nosc control bits. if they are the same, then the clock switch is a redundant operation. in this case, the oswen bit is cleared automatically and the clock switch is aborted. 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 transition. in addition, the nosc bit values are transferred to the cosc status bits. 6. the old clock source is turned off at this time, with the exception of lprc (if wdt or fscm are enabled) or lp (if lposcen remains set). 9.3 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. if an oscillator failure occurs, the fscm generates a clock failure trap event and switches the system clock over to the frc oscillator. then the application program can either attempt to restart the oscillator or execute a controlled shutdown. the trap can be treated as a warm reset by simply loading the reset address into the oscillator fail trap vector. if the pll multiplier is us ed to scale the system clock, the internal frc is also multiplied by the same factor on clock failure. es sentially, the device switches to frc with pll on a clock failure. note: primary oscillator mode has three different submodes (xt, hs and ec) which are determined by the poscmd<1:0> config- uration bits. while an application can switch to and from primary oscillator mode in software, it cannot switch between the different primary submodes without reprogramming the device. note 1: the processor continues to execute code throughout the clock switching sequence. timing sensitive code should not be executed during this time. 2: direct clock switches between any primary oscillator mode with pll and frcpll mode are not permitted. this applies to clock switches in either direction. in these instances, the application must switch to frc mode as a transition clock source between the two pll modes. 3: refer to section 7. ?oscillator?

? 2009 microchip technology inc. ds70175h-page 131 pic24hjxxxgpx06/x08/x10 10.0 power-saving features the pic24hjxxxgpx06/x08/x10 devices provide the ability to manage power consumption by selectively managing clocking to the cpu and the peripherals. in general, a lower clock frequency and a reduction in the number of circuits being clocked constitutes lower con- sumed power. pic24hj xxxgpx06/x08/x10 devices can manage power consumption in four different ways: ? clock frequency ? instruction-based sleep and idle modes ? software-controlled doze mode ? selective peripheral control in software combinations of these methods can be used to selec- tively tailor an application?s power consumption while still maintaining critical application features, such as timing-sensitive communications. 10.1 clock frequency and clock switching pic24hjxxxgpx06/x08/x10 devices allow a wide range of clock frequencies to be selected under appli- cation control. if the system clock configuration is not locked, users can choose low-power or high-precision oscillators by simply changing the nosc bits (osc- con<10:8>). the process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in section 9.0 ?oscillator configuration? . 10.2 instruction-based power-saving modes pic24hjxxxgpx06/x08/x10 devices have two spe- cial 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 c ode execution, but allows peripheral modules to continue operation. the assem- bly syntax of the pwrsav instruction is shown in example 10-1. 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?. 10.2.1 sleep mode sleep mode has these features: ? the system clock source is shut down. if an on-chip oscillator is used, it is turned off. ? the device current consumption is reduced to a minimum, provided that no i/o pin is sourcing current. ? the fail-safe clock monitor does not operate during sleep mode since the system clock source is disabled. ? the lprc clock continues to run in sleep mode if the wdt is enabled. ? the wdt, if enabled, is automatically cleared prior to entering sleep mode. ? some device features or peripherals may continue to operate in sleep mode. this includes items such as the input change notification on the i/o ports, or peripherals that use an external clock input. any peripheral that requires t he system clock source for its operation is disabled in sleep mode. 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, the processor restarts with the same clock source that was active when sleep mode was entered. example 10-1: pwrsav instruction syntax note: this data sheet summarizes the features of the pic24hjxxxg px06/x08/x10 fam- ily of devices. however, it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?pic24h family refer- ence manual? , section 9. ?watchdog timer and power-saving modes? (ds70236), which is available from the microchip website (www.microchip.com). note: sleep_mode and idle_mode are constants defined in the assembler include file for the selected device. pwrsav #sleep_mode ; put the device into sleep mode pwrsav #idle_mode ; put the device into idle mode
pic24hjxxxgpx06/x08/x10 ds70175h-page 132 ? 2009 microchip technology inc. 10.2.2 idle mode idle mode has these features: ? 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 10.4 ?peripheral module disable? ). ? if the wdt or fscm is enabled, the lprc also remains active. the device will wake from idle mode on any of these events: ? any interrupt that is individually enabled. ? any device reset. ? a wdt time-out. on wake-up from idle, the clock is reapplied to the cpu and instruction execution begins immediately, starting with the instruction following the pwrsav instruction, or the first instruction in the isr. 10.2.3 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. 10.3 doze mode generally, changing clock speed and invoking one of the power-saving modes are the preferred strategies for reducing power consumption. there may be cir- cumstances, however, where th is is not practical. for example, it may be necessary for an application to main- tain uninterrupted synchr onous communication, even while it is doing nothing else. reducing system clock speed may introduce communication errors, while using a power-saving mode may stop communications completely. doze mode is a simple and effective alternative method to reduce power consumption while the device is still executing code. in this mode, the system clock contin- ues to operate from the sa me source and at the same speed. peripheral modules continue to be clocked at the same speed, while the cpu clock speed is reduced. synchronizatio n 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 (clk- div<11>). the ratio between peripheral and core clock speed is determined by the doze<2:0> bits (clk- div<14:12>). there are eight possible configurations, from 1:1 to 1:128, with 1: 1 being the default setting. it is also possible to use doze mode to selectively reduce power consumption in event-driven applica- tions. this allows clock-sensitive functions, such as synchronous communicat ions, to continue without interruption while the cpu idles, waiting for something to invoke an interrupt routine. enabling the automatic return to full-speed cpu operation on interrupts is enabled by setting the roi bit (clkdiv<15>). by default, interrupt events have no effect on doze mode operation. for example, suppose the device is operating at 20 mips and the can module has been configured for 500 kbps based on this device operating speed. if the device is now placed in doze mode with a clock frequency ratio of 1:4, the can module continues to communicate at the required bit rate of 500 kbps, but the cpu now starts execut ing instructions at a frequency of 5 mips. 10.4 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 disabled via the appropriate pmd control bit, the peripheral is in a minimum power consumption state. the control and status registers associated with the peripheral are also disabled, so writes to those registers will have no effect and read values will be invalid. a peripheral module is only enabled if both the associ- ated 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 mod- ule is disabled after a delay of 1 instruction cycle. similarly, if a pmd bit is cleared, the corresponding module is enabled after a delay of 1 instruction cycle (assuming the module control registers are already configured to enable module operation).

(i 2 c?) the inter-integrated circuit (i 2 c) module provides complete hardware support for both slave and multi- master modes of the i 2 c serial communication standard, with a 16-bit interface. the pic24hjxxxgpx06/x08/ x10 devices have up to two i 2 c interface modules, denoted as i2c1 and i2c2. each i 2 c module has a 2-pin interface: the sclx pin is clock and the sdax pin is data. each i 2 c module ?x? (x = 1 or 2) offers the following key features: ?i 2 c interface supporting both master and slave operation. ?i 2 c slave mode supports 7 and 10-bit address. ?i 2 c master mode supports 7 and 10-bit address. ?i 2 c port allows bidirectional transfers between master and slaves. ? serial clock synch ronization for i 2 c port can be used as a handshake mechanism to suspend and resume serial transfe r (sclrel control). ?i 2 c supports multi-master operation; detects bus collision and will arbitrate accordingly. 17.1 operating modes the hardware fully implements all the master and slave functions of the i 2 c standard and fast mode specifications, as well as 7 and 10-bit addressing. the i 2 c module can operate either as a slave or a master on an i 2 c bus. the following types of i 2 c operation are supported: ?i 2 c slave operation with 7-bit address ?i 2 c slave operation with 10-bit address ?i 2 c master operation with 7 or 10-bit address for details about the communication sequence in each of these modes, please refer to the ?pic24h family reference manual? . 17.2 i 2 c registers i2cxcon and i2cxstat are control and status registers, respectively. the i2cxcon register is readable and writable. the lower six bits of i2cxstat are read-only. the remaining bits of the i2cstat are read/write. i2cxrsr is the shift register used for shifting data, whereas i2cxrcv is the buffer register to which data bytes are written, or from which data bytes are read. i2cxrcv is the receive buff er. i2cxtrn is the transmit register to which bytes ar e written during a transmit operation. the i2cxadd register holds the slave address. a status bit, add10, indicates 10-bit address mode. the i2cxbrg acts as the baud rate generator (brg) reload value. in receive operations, i2cxrsr and i2cxrcv together form a double-buffered receiver. when i2cxrsr receives a complete byte, it is transferred to i2cxrcv and an interrupt pulse is generated. note: this data sheet summarizes the features of the pic24hjxxxg px06/x08/x10 fam- ily of devices. however, it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?pic24h family refer- ence manual? , section 19. ?inter-inte- grated circuit?

(ds70225), which is available from the microchip website (www.microchip.com). note: the adc module needs to be disabled before modifying the ad12b bit.

(icsp?) programming capability ? in-circuit emulation 21.1 configuration bits the configuration bits can be programmed (read as ? 0 ?), or left unprogrammed (read as ? 1 ?), to select vari- ous device configurations. these bits are mapped starting at program memory location 0xf80000. the device configuration register map is shown in table 21-1. the individual configuration bit descriptions for the fbs, fss, fgs, foscsel, fosc, fwdt and fpor configuration registers are shown in table 21-2. note that address 0xf80000 is beyond the user program memory space. in fact, it belongs to the configuration memory space (0x800000-0xffffff), which can only be accessed using table reads and table writes. the upper byte of all devi ce configuration registers should always be ? 1111 1111 ?. this makes them appear to be nop instructions in the remote event that their locations are ever executed by accident. since configuration bits are not implemented in the corresponding locations, writing ? 1 ?s to these locations has no effect on device operation. to prevent inadvertent configuration changes during code execution, all progr ammable configuration bits are write-once. after a bit is initially programmed during a power cycle, it cannot be written to again. changing a device configuration requires that power to the device be cycled. table 21-1: device configuration register map note: this data sheet summarizes the features of the pic24hjxxxg px06/x08/x10 fam- ilies of devices. however, it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 23. ?code- guard? security?
