dsPIC33FJXXXGPX06A/X08A/X10A 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 8MHz for start-up with PLL enabled to comply with device PLL start-up conditions. This means that if the external oscillator frequency is outside this range, the application must start-up in the FRC mode first. The default PLL settings after a POR with an oscillator frequency outside this range will violate the device operating speed. Once the device powers up, the application firmware can initialize the PLL SFRs, CLKDIV and PLLDBF to a suitable value, and then perform a clock switch to the Oscillator + PLL clock source. Note that clock switching must be enabled in the device Configuration word. 2.8 Configuration of Analog and Digital Pins During ICSP Operations If MPLAB ICD 3 or REAL ICE is selected as a debug- ger, it automatically initializes all of the A/D input pins (ANx) as “digital” pins, by setting all bits in the ADPCFG and ADPCFG2 registers. The bits in the registers that correspond to the A/D pins that are initialized by ICD 3 or REAL ICE, must not be cleared by the user application firmware; otherwise, communication errors will result between the debugger and the device. If your application needs to use certain A/D pins as analog input pins during the debug session, the user application must clear the corresponding bits in the ADPCFG and ADPCFG2 registers during initialization of the ADC module. When ICD 3 or REAL ICE is used as a programmer, the user application firmware must correctly configure the ADPCFG and ADPCFG2 registers. Automatic initialization of these registers is only done during debugger operation. Failure to correctly configure the register(s) will result in all A/D pins being recognized as analog input pins, resulting in the port value being read as a logic ‘0’, which may affect user application functionality. 2.9 Unused I/Os Unused I/O pins should be configured as outputs and driven to a logic-low state. Alternatively, connect a 1k to 10k resistor between VSS and the unused pins. DS70593D-page 26  2009-2012 Microchip Technology Inc.

dsPIC33FJXXXGPX06A/X08A/X10A 4.2.5 X AND Y DATA SPACES 4.2.6 DMA RAM The core has two data spaces, X and Y. These data Every dsPIC33FJXXXGPX06A/X08A/X10A device spaces can beconsidered either separate (for some contains 2 Kbytes of dual ported DMA RAM located at DSP instructions), or as one unified linear address the end of Y data space. Memory locations is part of Y range (for MCU instructions). The data spaces are data RAM and is in the DMA RAM space are accessible accessed using two Address Generation Units (AGUs) simultaneously by the CPU and the DMA controller and separate data paths. This feature allows certain module. DMA RAM is utilized by the DMA controller to instructions to concurrently fetch two words from RAM, store data to be transferred to various peripherals using thereby enabling efficient execution of DSP algorithms DMA, as well as data transferred from various such as Finite Impulse Response (FIR) filtering and peripherals using DMA. The DMA RAM can be Fast Fourier Transform (FFT). accessed by the DMA controller without having to steal cycles from the CPU. The X data space is used by all instructions and supports all addressing modes. There are separate When the CPU and the DMA controller attempt to read and write data buses for X data space. The X read concurrently write to the same DMA RAM location, the data bus is the read data path for all instructions that hardware ensures that the CPU is given precedence in view data space as combined X and Y address space. accessing the DMA RAM location. Therefore, the DMA It is also the X data prefetch path for the dual operand RAM provides a reliable means of transferring DMA DSP instructions (MAC class). data without ever having to stall the CPU. The Y data space is used in concert with the X data Note: DMA RAM can be used for general space by the MAC class of instructions (CLR, ED, purpose data storage if the DMA function EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide is not required in an application. two concurrent data read paths. Both the X and Y data spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X data space. All data memory writes, including in DSP instructions, view data space as combined X and Y address space. The boundary between the X and Y data spaces is device-dependent and is not user-programmable. All effective addresses are 16 bits wide and point to bytes within the data space. Therefore, the data space address range is 64 Kbytes, or 32K words, though the implemented memory locations vary by device.  2009-2012 Microchip Technology Inc. DS70593D-page 45

As is C the case for the Stack Pointer, SPLIM<0> is forced to ‘0’ because all stack oper- 3 ations must be word-aligned. Whenever an EA is generated using W15 as a 3 source or destination pointer, the resulting address is compared with the value F 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 J stack error trap will occur on a subsequent push operation. Thus, for example, X if it is desirable to cause a stack error trap when the stack grows beyond X address 0x2000 in RAM, initialize the SPLIM with the value 0x1FFE. X Similarly, a Stack Pointer underflow (stack error) trap is generated when the G Stack Pointer address is found to be less than 0x0800. This prevents the stack from interfering with the Special Function Register (SFR) space.

Individual instructions may support different subsets of these addressing modes. TABLE 4-35: FUNDAMENTAL ADDRESSING MODES SUPPORTED 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 (incremented or decremented) by a signed constant value to form the EA. Register Indirect with Register Offset The sum of Wn and Wb forms the EA. Register Indirect with Literal Offset The sum of Wn and a literal forms the EA. 4.3.3 MOVE AND ACCUMULATOR • Register Indirect with Literal Offset INSTRUCTIONS • 8-bit Literal Move instructions and the DSP accumulator class of • 16-bit Literal instructions provide a greater degree of addressing Note: Not all instructions support all the flexibility than other instructions.

For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI instruction uses a 14-bit unsigned literal field. In some instructions, such as ADD Acc, the source of an operand or result is implied by the opcode itself. Certain operations, such as NOP, do not have any operands. 4.4 Modulo Addressing Modulo Addressing mode is a method of providing an automated means to support circular data buffers using hardware. The objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many DSP algorithms. Modulo Addressing can operate in either data or program space (since the data pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into program space) and Y data spaces. Modulo Addressing can operate on any W register pointer. However, it is not advisable to use W14 or W15 for Modulo Addressing since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. In general, any particular circular buffer can only be configured to operate in one direction as there are certain restrictions on the buffer start address (for incre- menting buffers), or end address (for decrementing buffers), based upon the direction of the buffer. The only exception to the usage restrictions is for buffers which have a power-of-2 length. As these buffers satisfy the start and end address criteria, they may operate in a bidirectional mode (i.e., address boundary checks will be performed on both the lower and upper address boundaries).  2009-2012 Microchip Technology Inc.

It has the PC to zero. The digital signal controller then begins the following features: program execution at location 0x000000. The user • Up to eight processor exceptions and software programs a GOTO instruction at the Reset address traps which redirects program execution to the appropriate • Seven user-selectable priority levels start-up routine. • Interrupt Vector Table (IVT) with up to 118 vectors Note: Any unimplemented or unused vector • A unique vector for each interrupt or exception locations in the IVT and AIVT should be source programmed with the address of a default • Fixed priority within a specified user priority level interrupt handler routine that contains a • Alternate Interrupt Vector Table (AIVT) for debug RESET instruction. support • Fixed interrupt entry and return latencies 7.1 Interrupt Vector Table The Interrupt Vector Table is shown in Figure7-1. The IVT resides in program memory, starting at location 000004h. The IVT contains 126 vectors consisting of eightnon-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. All other things being equal, lower addresses have a higher natural priority. For example, the interrupt associated with vector 0 will take priority over interrupts at any other vector address. dsPIC33FJXXXGPX06A/X08A/X10A devices imple- ment up to 67 unique interrupts and five non-maskable traps. These are summarized in Table7-1 and Table7-2.  2009-2012 Microchip Technology Inc. DS70593D-page 89

Each user interrupt source can be assigned to one of eight priority levels. dsPIC33FJXXXGPX06A/X08A/X10A devices imple- The INTTREG register contains the associated ment a total of 30 registers for the interrupt controller: interrupt vector number and the new CPU interrupt • INTCON1 priority level, which are latched into vector number • INTCON2 (VECNUM<6:0>) and Interrupt level bits (ILR<3:0>) in • IFS0 through IFS4 the INTTREG register. The new interrupt priority level is the priority of the pending interrupt. • IEC0 through IEC4 • IPC0 through IPC17 The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence that they are • INTTREG listed in Table7-1. For example, the INT0 (External Global interrupt control functions are controlled from Interrupt 0) is shown as having vector number 8 and a INTCON1 and INTCON2. INTCON1 contains the natural order priority of 0. Thus, the INT0IF bit is found Interrupt Nesting Disable (NSTDIS) bit as well as the in IFS0<0>, the INT0IE bit in IEC0<0>, and the INT0IP control and status flags for the processor trap sources. bits in the first position of IPC0 (IPC0<2:0>).

In general, the user must clear the interrupt flag in the appropriate IFSx register for the source of interrupt that the ISR handles. Otherwise, the ISR will be re-entered immediately after exiting the routine. If the ISR is coded in assembly language, it must be terminated using a RETFIE instruction to unstack the saved PC value, SRL value and old CPU priority level.  2009-2012 Microchip Technology Inc.

The serial interface consists of 4 pins: SDIx (serial data input), SDOx (serial data output), SCKx (shift clock input or output), and SSx (active-low slave select). In Master mode operation, SCK is a clock output but in Slave mode, it is a clock input.

FRMEN (SPIxCON2<15>) = 1 and SSEN (SPIxCON1<7>) = 1 are exclusive and invalid. In Frame mode, SCKx is continuous and the Frame sync pulse is active on the SSx pin, which indicates the start of a data frame. Note: Not all third-party devices support Frame mode timing. Refer to the SPI electrical characteristics for details. 4. In Master mode only, set the SMP bit (SPIxCON1<9>) to a ‘1’ for the fastest SPI data rate possible. The SMP bit can only be set at the same time or after the MSTEN bit (SPIxCON1<5>) is set. 5. To avoid invalid slave read data to the master, the user’s master software must guarantee enough time for slave software to fill its write buf- fer before the user application initiates a master write/read cycle. It is always advisable to pre- load the SPIxBUF transmit register in advance of the next master transaction cycle. SPIxBUF is transferred to the SPI shift register and is empty once the data transmission begins. DS70593D-page 182  2009-2012 Microchip Technology Inc.

On devices with a DMA module, the ADC mod- ule has only 1 ADC result buffer, (i.e., ADC1BUF0), per ADC peripheral and the ADC conversion result must be read either by the CPU or DMA controller before the next ADC conversion is complete to avoid overwriting the previous value. 4. The DONE bit (AD1CON1<0>) is only cleared at the start of each conversion and is set at the completion of the conversion, but remains set indefinitely even through the next sample phase until the next conversion begins. If application code is monitoring the DONE bit in any kind of software loop, the user must consider this behavior because the CPU code execution is faster than the ADC. As a result, in manual sam- ple mode, particularly where the users code is setting the SAMP bit (AD1CON1<1>), the DONE bit should also be cleared by the user application just before setting the SAMP bit. 5. On devices with two ADC modules, the ADCxPCFG registers for both ADC modules must be set to a logic ‘1’ to configure a target I/O pin as a digital I/O pin. Failure to do so means that any alternate digital input function will always see only a logic ‘0’ as the digital input buffer is held in Disable mode.

The code protection features are controlled by the Configuration registers: FBS, FSS and FGS. Note: Refer to Section 23. “CodeGuard™ Security” (DS70199) in the “dsPIC33F/ PIC24H Family Reference Manual” for fur- ther information on usage, configuration and operation of CodeGuard™ Security. 22.7 In-Circuit Serial Programming dsPIC33FJXXXGPX06A/X08A/X10A family digital sig- nal controllers can be serially programmed while in the end application circuit. This is simply done with two lines for clock and data and three other lines for power, ground and the programming sequence. This allows customers to manufacture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. This also allows the most recent firmware or a custom firmware, to be programmed. Please refer to the “dsPIC33F/PIC24H Flash Programming Specification” (DS70152) document for details about ICSP. Any one out of three pairs of programming clock/data pins may be used: • PGEC1 and PGED1 • PGEC2 and PGED2 • PGEC3 and PGED3 DS70593D-page 258  2009-2012 Microchip Technology Inc.

However, it is not ‘Ws’ or ‘f’) intended to be a comprehensive • The bit in the W register or file register reference source. To complement the (specified by a literal value or indirectly by the information in this data sheet, refer to the contents of register ‘Wb’) latest family reference sections of the “dsPIC33F/PIC24H Family Reference The literal instructions that involve data movement may Manual”, which are available from the use some of the following operands: Microchip web site (www.microchip.com). • A literal value to be loaded into a W register or file register (specified by the value of ‘k’) The dsPIC33F instruction set is identical to that of the dsPIC30F. • The W register or file register where the literal value is to be loaded (specified by ‘Wb’ or ‘f’) Most instructions are a single program memory word (24 bits). Only three instructions require two program However, literal instructions that involve arithmetic or memory locations. logical operations use some of the following operands: Each single-word instruction is a 24-bit word, divided • The first source operand which is a register ‘Wb’ into an 8-bit opcode, which specifies the instruction without any address modifier type and one or more operands, which further specify • The second source operand which is a literal the operation of the instruction. value The instruction set is highly orthogonal and is grouped • The destination of the result (only if not the same into five basic categories: as the first source operand) which is typically a register ‘Wd’ with or without an address modifier • Word or byte-oriented operations The MAC class of DSP instructions may use some of the • Bit-oriented operations following operands: • Literal operations • The accumulator (A or B) to be used (required • DSP operations operand) • Control operations • The W registers to be used as the two operands Table23-1 illustrates the general symbols used in • The X and Y address space prefetch operations describing the instructions. • The X and Y address space prefetch destinations The dsPIC33F instruction set summary in Table23-2 • The accumulator write back destination provides all the instructions, along with the status flags affected by each instruction. The other DSP instructions do not involve any multiplication and may include: Most word or byte-oriented W register instructions (including barrel shift instructions) have three • The accumulator to be used (required) operands: • The source or destination operand (designated as Wso or Wdo, respectively) with or without an • The first source operand which is typically a address modifier register ‘Wb’ without any address modifier • The amount of shift specified by a W register ‘Wn’ • The second source operand which is typically a or a literal value register ‘Ws’ with or without an address modifier • The destination of the result which is typically a The control instructions may use some of the following register ‘Wd’ with or without an address modifier operands: However, word or byte-oriented file register instructions • A program memory address have two operands: • The mode of the table read and table write instructions • The file register specified by the value ‘f’ • The destination, which could either be the file register ‘f’ or the W0 register, which is denoted as ‘WREG’  2009-2012 Microchip Technology Inc.

dsPIC33FJXXXGPX06A/X08A/X10A 26.0 HIGH TEMPERATURE ELECTRICAL CHARACTERISTICS This section provides an overview of dsPIC33FJXXXGPX06A/X08A/X10A electrical characteristics for devices operating in an ambient temperature range of -40°C to +150°C. The specifications between -40°C to +150°C are identical to those shown in Section25.0 “Electrical Characteristics” for operation between -40°C to +125°C, with the exception of the parameters listed in this section. Parameters in this section begin with an H, which denotes High temperature. For example, parameter DC10 in Section25.0 “Electrical Characteristics” is the Industrial and Extended temperature equivalent of HDC10. Absolute maximum ratings for the dsPIC33FJXXXGPX06A/X08A/X10A high temperature devices are listed below. Exposure to these maximum rating conditions for extended periods can affect device reliability. Functional operation of the device at these or any other conditions above the parameters indicated in the operation listings of this specification is not implied. Absolute Maximum Ratings (See Note 1) Ambient temperature under bias(4).........................................................................................................-40°C to +150°C Storage temperature.............................................................................................................................. -65°C to +160°C Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +4.0V Voltage on any pin that is not 5V tolerant with respect to VSS(5) ....................................................-0.3V to (VDD + 0.3V) Voltage on any 5V tolerant pin with respect to VSS when VDD < 3.0V(5) ....................................... -0.3V to (VDD + 0.3V) Voltage on any 5V tolerant pin with respect to VSS when VDD  3.0V(5) .................................................... -0.3V to 5.6V Voltage on VCAP with respect to VSS ...................................................................................................... 2.25V to 2.75V Maximum current out of VSS pin.............................................................................................................................60 mA Maximum current into VDD pin(2).............................................................................................................................60 mA Maximum junction temperature.............................................................................................................................+155°C Maximum current sourced/sunk by any 2x I/O pin(3)................................................................................................2 mA Maximum current sourced/sunk by any 4x I/O pin(3)................................................................................................4 mA Maximum current sourced/sunk by any 8x I/O pin(3)................................................................................................8 mA Maximum current sunk by all ports combined ........................................................................................................10 mA Maximum current sourced by all ports combined(2)................................................................................................10 mA Note1: Stresses above those listed under “Absolute Maximum Ratings” can cause permanent damage to the device. This is a stress rating only, and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods can affect device reliability. 2: Maximum allowable current is a function of device maximum power dissipation (see Table26-2). 3: Unlike devices at 125°C and below, the specifications in this section also apply to the CLKOUT, VREF+, VREF-, SCLx, SDAx, PGECx, and PGEDx pins. 4: AEC-Q100 reliability testing for devices intended to operate at 150°C is 1,000 hours. Any design in which the total operating time from 125°C to 150°C will be greater than 1,000 hours is not warranted without prior written approval from Microchip Technology Inc. 5: Refer to the “Pin Diagrams” section for 5V tolerant pins.  2009-2012 Microchip Technology Inc.

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