Extract Chip PIC16F685 Code

We can Extract Chip PIC16F685 Code, please view the Chip PIC16F685 features for your reference:

The PIC16F685 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 PIC16F677/PIC16F687, and the first 4K x 14 (0000h-0FFFh) for the PIC16F685/PIC16F689/ PIC16F690 when Extract Chip. Accessing a location above these boundaries will cause a wraparound. The Reset vector is at 0000h and the interrupt vector is at 0004h.

The data memory (see Figures 2-6 through 2-8) is partitioned into four banks which contain the General Purpose Registers (GPR) and the Special Function Registers (SFR). The Special Function Registers are located in the first 32 locations of each bank. The CALL, RETURN RETFIE, RETLW after Extract Chip.

General Purpose Registers, implemented as static RAM, are located in the last 96 locations of each Bank. Register locations F0h-FFh in Bank 1, 170h-17Fh in Bank 2 and 1F0h-1FFh in Bank 3 point to addresses 70h-7Fh in Bank 0. The actual number of General Purpose Resisters (GPR) in each Bank depends on the device. Details are shown in Figures 2-4 through 2-8 for Extract Chip.

All other RAM is unimplemented and returns ‘0’ when Reset Vector 0000h read. RP<1:0> of the STATUS register are the bank select bits:

The register file is organized as 128 x 8 in the PIC16F687   and   256   x   8   in   the PIC16F685/PIC16F689/PIC16F690. Each register is accessed, either directly or indirectly, through the File Select Register (FSR) (see Section 2.4 “Indirect Addressing, INDF and FSR Registers”) if Extract Chip.


The Special Function Registers are registers used by the CPU and peripheral functions for controlling the desired operation of the device (see Tables 2-1 through 2-4). These registers are static RAM before Extract Chip.

The special registers can be classified into two sets: core and peripheral. The Special Function Registers associated with the “core” are described in this section. Registers related to the operation of peripheral features are described in the section of that peripheral feature after Extract Chip.
