PIC24HJXXXGPX06A/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 AD1PCFGL register. The bits in this register that correspond to the A/D 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 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 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 between VSS and the unused pins. DS70592D-page 22  2009-2012 Microchip Technology Inc.

Overhead-free, single-cycle program loop constructs are supported using the REPEAT instruction, which is interruptible at any point. The PIC24HJXXXGPX06A/X08A/X10A devices have sixteen, 16-bit working registers in the programmer’s model. Each of the working registers can serve as a data, address or address offset register. The 16th working register (W15) operates as a software Stack Pointer (SP) for interrupts and calls. The PIC24HJXXXGPX06A/X08A/X10A instruction set includes many addressing modes and is designed for optimum C compiler efficiency. For most instructions, the PIC24HJXXXGPX06A/X08A/X10A 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.

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.

The IVT resides in program memory, starting at location 000004h. The IVT contains 126 vectors consisting of 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. PIC24HJXXXGPX06A/X08A/X10A devices implement up to 61 unique interrupts and 5 nonmaskable traps. These are summarized in Table7-1 and Table7-2.  2009-2012 Microchip Technology Inc. DS70592D-page 69

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.

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. DS70592D-page 160  2009-2012 Microchip Technology Inc.

Each I2C module ‘x’ (x = 1 or 2) offers the following key features: • I2C interface supporting both master and slave operation • I2C Slave mode supports 7-bit and 10-bit addressing • I2C Master mode supports 7-bit and 10-bit addressing • I2C Port allows bidirectional transfers between master and slaves • Serial clock synchronization for I2C port can be used as a handshake mechanism to suspend and resume serial transfer (SCLREL control) • I2C supports multi-master operation; detects bus collision and will arbitrate accordingly  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.

Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at “min.” values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the “max.” cycle time limit is “DC” (no clock) for all devices. 3: Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin. 4: Data for this parameter is Preliminary. This parameter is characterized, but not tested in manufacturing.  2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A 25.0 HIGH TEMPERATURE ELECTRICAL CHARACTERISTICS This section provides an overview of PIC24HJXXXGPX06A/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 Section24.0 “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 Section24.0 “Electrical Characteristics” is the Industrial and Extended temperature equivalent of HDC10. Absolute maximum ratings for the PIC24HJXXXGPX06A/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 Table25-2). 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.
