Break IC PIC16F687 Firmware

It is also very important to understand the peripheral features when Break IC PIC16F687 Firmware

Peripheral Features:

· 17 I/O pins and 1 input only pin:

– High current source/sink for direct LED drive

– Interrupt-on-Change pin

– Individually programmable weak pull-ups

– Ultra Low-Power Wake-up (ULPWU)

· Analog Comparator module with:

– Two analog comparators

– Programmable on-chip voltage reference (CVREF) module (% of VDD)

– Comparator inputs and outputs externally accessible which can be used for Copy MCU PIC16C72 Software

– SR Latch mode

– Timer 1 Gate Sync Latch

– Fixed 0.6V VREF

· Timer0: 8-bit timer/counter with 8-bit programmable prescaler

· Enhanced Timer1:

– 16-bit timer/counter with prescaler

– External Timer1 Gate (count enable)

– Option to use OSC1 and OSC2 in LP mode as Timer1 oscillator if INTOSC mode selected

· Timer2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler

· Enhanced Capture, Compare, PWM+ module:

– 16-bit Capture, max resolution 12.5 ns

– Compare, max resolution 200 ns

– 10-bit PWM with 1, 2 or 4 output channels, programmable “dead time”, max frequency 20 kHz

– PWM output steering control which can be manipulated to Break MCU PIC16C717 Program

· Synchronous Serial Port (SSP):

– SPI mode (Master and Slave)

· I2C™ (Master/Slave modes):

– I2C™ address mask

· In-Circuit Serial ProgrammingTM (ICSPTM) via two pins for the purpose

Program Memory Organization

The PIC16F687 has a 13-bit program counter capable of addressing an 8K x 14 program memory space. Only the first 1K x 14 (0000h-03FFh) is physically implemented for the PIC16F631, the first 2K x 14 (0000h-07FFh) for the PIC16F687, and the first 4K x 14 (0000h-0FFFh) for the PIC16F687. Accessing a location above these

boundaries will cause a wraparound. The Reset vector is at 0000h and the interrupt vector is at 0004h.
