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.

Note: This data sheet summarizes the features Consider the following criteria when using decoupling of the PIC24HJXXXGPX06/X08/X10 capacitors: family of devices. It is not intended to be a comprehensive reference source. To • Value and type of capacitor: Recommendation complement the information in this data of 0.1 µF (100 nF), 10-20V. This capacitor should sheet, refer to the “PIC24H Family be a low-ESR and have resonance frequency in Reference Manual”, which is available the range of 20MHz and higher. It is from the Microchip website recommended that ceramic capacitors be used. (www.microchip.com). • Placement on the printed circuit board: The decoupling capacitors should be placed as close 2.1 Basic Connection Requirements to the pins as possible. It is recommended to place the capacitors on the same side of the Getting started with the PIC24HJXXXGPX06/X08/X10 board as the device. If space is constricted, the family of 16-bit Microcontrollers (MCUs) requires capacitor can be placed on another layer on the attention to a minimal set of device pin connections PCB using a via; however, ensure that the trace before proceeding with development. The following is a length from the pin to the capacitor is within list of pin names, which must always be connected: one-quarter inch (6mm) in length. • All VDD and VSS pins • Handling high frequency noise: If the board is (see Section2.2 “Decoupling Capacitors”) experiencing high frequency noise, upward of • All AVDD and AVSS pins (regardless if ADC module tens of MHz, add a second ceramic-type capacitor is not used) in parallel to the above described decoupling (see Section2.2 “Decoupling Capacitors”) capacitor. The value of the second capacitor can • VCAP/VDDCORE be in the range of 0.01µF to 0.001µF. Place this (see Section2.3 “Capacitor on Internal Voltage second capacitor next to the primary decoupling Regulator (VCAP/VDDCORE)”) capacitor. In high-speed circuit designs, consider implementing a decade pair of capacitances as • MCLR pin close to the power and ground pins as possible. (see Section2.4 “Master Clear (MCLR) Pin”) For example, 0.1 µF in parallel with 0.001 µF. • PGECx/PGEDx pins used for In-Circuit Serial • Maximizing performance: On the board layout Programming™ (ICSP™) and debugging purposes from the power supply circuit, run the power and (see Section2.5 “ICSP Pins”) return traces to the decoupling capacitors first, • OSC1 and OSC2 pins when external oscillator and then to the device pins. This ensures that the source is used decoupling capacitors are first in the power chain. (see Section2.6 “External Oscillator Pins”) Equally important is to keep the trace length Additionally, the following pins may be required: between the capacitor and the power pins to a minimum thereby reducing PCB track inductance. • VREF+/VREF- pins used when external voltage reference for ADC module is implemented Note: The AVDD and AVSS pins must be connected independent of the ADC voltage reference source. © 2009 Microchip Technology Inc.

This means that if the external oscillator frequency is outside this range, the application must start-up in the FRC mode first. The default PLL settings after a POR with an oscillator frequency outside this range will violate the device operating speed. Once the device powers up, the application firmware can initialize the PLL SFRs, CLKDIV and PLLDBF to a suitable value, and then perform a clock switch to the Oscillator + PLL clock source. Note that clock switching must be enabled in the device Configuration word. 2.8 Configuration of Analog and Digital Pins During ICSP Operations If MPLAB ICD 2, ICD 3 or REAL ICE is selected as a debugger, it automatically initializes all of the A/D input pins (ANx) as “digital” pins, by setting all bits in the AD1PCFGL register. The bits in this register that correspond to the A/D pins that are initialized by MPLAB ICD 2, ICD 3, or REAL ICE, must not be cleared by the user application firmware; otherwise, communication errors will result between the debugger and the device. If your application needs to use certain A/D pins as analog input pins during the debug session, the user application must clear the corresponding bits in the AD1PCFGL register during initialization of the ADC module. When MPLAB ICD 2, ICD 3 or REAL ICE is used as a programmer, the user application firmware must correctly configure the AD1PCFGL register. Automatic initialization of this register is only done during debugger operation. Failure to correctly configure the register(s) will result in all A/D pins being recognized as analog input pins, resulting in the port value being read as a logic ‘0’, which may affect user application functionality. 2.9 Unused I/Os Unused I/O pins should be configured as outputs and driven to a logic-low state. Alternatively, connect a 1k to 10k resistor to VSS on unused pins and drive the output to logic low. DS70175H-page 18 © 2009 Microchip Technology Inc.

The PIC24HJXXXGPX06/X08/X10 instruction set includes many addressing modes and is designed for optimum C compiler efficiency. For most instructions, the PIC24HJXXXGPX06/X08/X10 is capable of executing a data (or program data) memory read, a working register (data) read, a data memory write and a program (instruction) memory read per instruction cycle. As a result, three parameter instructions can be supported, allowing A + B = C operations to be executed in a single cycle.

The addressing with the Stack Pointer sets an upper address boundary modes provided in the MAC class of instructions are for the stack. SPLIM is uninitialized at Reset. As is the case for the Stack Pointer, SPLIM<0> is forced to ‘0’ somewhat different from those in the other instruction types. because all stack operations must be word-aligned. Whenever an EA is generated using W15 as a source 4.3.1 FILE REGISTER INSTRUCTIONS or destination pointer, the resulting address is compared with the value in SPLIM. If the contents of Most file register instructions use a 13-bit address field the Stack Pointer (W15) and the SPLIM register are (f) to directly address data present in the first 8192 equal and a push operation is performed, a stack error bytes of data memory (Near Data Space). Most file trap will not occur. The stack error trap will occur on a register instructions employ a working register, W0, subsequent push operation. Thus, for example, if it is which is denoted as WREG in these instructions. The desirable to cause a stack error trap when the stack destination is typically either the same file register or grows beyond address 0x2000 in RAM, initialize the WREG (with the exception of the MUL instruction), SPLIM with the value 0x1FFE. which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can Similarly, a Stack Pointer underflow (stack error) trap is access the entire data space. generated when the Stack Pointer address is found to be less than 0x0800. This prevents the stack from 4.3.2 MCU INSTRUCTIONS interfering with the Special Function Register (SFR) space. The 3-operand MCU instructions are of the form: A write to the SPLIM register should not be immediately Operand 3 = Operand 1 <function> Operand 2 followed by an indirect read operation using W15. where Operand 1 is always a working register (i.e., the addressing mode can only be Register Direct) which is FIGURE 4-5: CALL STACK FRAME referred to as Wb. Operand 2 can be a W register, fetched from data memory, or a 5-bit literal. The result 0x0000 15 0 location can be either a W register or a data memory location.

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.

The IVT contains 126 vectors consisting of RESET instruction. 8nonmaskable 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. PIC24HJXXXGPX06/X08/X10 devices implement up to 61 unique interrupts and 5 nonmaskable traps. These are summarized in Table7-1 and Table7-2. © 2009 Microchip Technology Inc. DS70175H-page 67

PIC24HJXXXGPX06/X08/X10 7.3 Interrupt Control and Status The IPC registers are used to set the interrupt priority Registers level for each source of interrupt. Each user interrupt source can be assigned to one of eight priority levels. PIC24HJXXXGPX06/X08/X10 devices implement a The INTTREG register contains the associated inter- total of 30 registers for the interrupt controller: rupt vector number and the new CPU interrupt priority • INTCON1 level, which are latched into vector number (VEC- • INTCON2 NUM<6:0>) and Interrupt level (ILR<3:0>) bit fields 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 Inter- natural order priority of 0. Thus, the INT0IF bit is found rupt Nesting Disable (NSTDIS) bit as well as the control in IFS0<0>, the INT0IE bit in IEC0<0>, and the INT0IP and status flags for the processor trap sources.

DISI instruction. 7.4.2 INTERRUPT SERVICE ROUTINE The method that is used to declare an ISR and initialize the IVT with the correct vector address will depend on the programming language (i.e., C or assembler) and the language development toolsuite that is used to develop the application. In general, the user must clear the interrupt flag in the appropriate IFSx register for the source of interrupt that the ISR handles. Otherwise, the ISR will be re-entered immediately after exiting the routine. If the ISR is coded in assembly language, it must be terminated using a RETFIE instruction to unstack the saved PC value, SRL value and old CPU priority level.

PIC24HJXXXGPX06/X08/X10 For example, suppose a 10 MHz crystal is being used, EQUATION 9-3: XT WITH PLL MODE with “XT with PLL” being the selected oscillator mode. EXAMPLE 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 FCY = F----O--2--S---C-- = 12---⎝⎛1---0---0---0----02---0-⋅-0--2-0-----⋅---3---2--⎠⎞ = 40 MIPS 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> = 0, then N2 = 2. This provides a Fosc of 160/2 = 80 MHz. The resultant device operating speed is 80/2 = 40 MIPS.

These modes include: ately after the CAN module has been • Initialization Mode placed in that mode of operation, the mod- • Disable Mode ule waits for 11 consecutive recessive bits • Normal Operation Mode on the bus before starting transmission. If • Listen Only Mode the user switches to Disable mode within • Listen All Messages Mode this 11-bit period, then this transmission is • Loopback Mode aborted and the corresponding TXABT bit is set and TXREQ bit is cleared. Modes are requested by setting the REQOP<2:0> bits (CiCTRL1<10:8>). Entry into a mode is Acknowledged 19.3.3 NORMAL OPERATION MODE by monitoring the OPMODE<2:0> bits Normal Operation mode is selected when (CiCTRL1<7:5>). The module will not change the mode REQOP<2:0>=000. In this mode, the module is and the OPMODE bits until a change in mode is activated and the I/O pins will assume the CAN bus acceptable, generally during bus Idle time, which is functions. The module will transmit and receive CAN defined as at least 11 consecutive recessive bits. bus messages via the CiTX and CiRX pins. 19.3.1 INITIALIZATION MODE 19.3.4 LISTEN ONLY MODE In the Initialization mode, the module will not transmit or If the Listen Only mode is activated, the module on the receive.

The transmit and remain and the error counters will retain their value. receive pins revert to their port I/O function. If the REQOP<2:0> bits (CiCTRL1<10:8>) = 001, the module will enter the Module Disable mode. If the module is active, the module will wait for 11 recessive bits on the CAN bus, detect that condition as an Idle bus, then accept the module disable command. When the OPMODE<2:0> bits (CiCTRL1<7:5>)=001, that indi- cates whether the module successfully went into Module Disable mode. The I/O pins will revert to normal I/O function when the module is in the Module Disable mode. The module can be programmed to apply a low-pass filter function to the CiRX input line while the module or the CPU is in Sleep mode. The WAKFIL bit (CiCFG2<14>) enables or disables the filter. © 2009 Microchip Technology Inc. DS70175H-page 177
