The PIC16F688 has a 13-bit program counter capable of addressing a 4K x 14 program memory space. Only the first 4K x 14 (0000h-01FFF) for the PIC16F688 is physically implemented. Accessing a location above these boundaries will cause a wraparound within the first 4K x 14 space. The Reset vector is at 0000h and the interrupt vector is at 0004h. The data memory is partitioned into multiple banks, which contain the General Purpose Registers (GPR) and the Special Function Registers (SFR). Bits RP0 and RP1 are bank select bits.Each bank extends up to 7Fh (128 bytes). The lower locations of each bank are reserved for the Special Function Registers. Above the Special Function Registers are the General Purpose Registers, implemented as static RAM. All implemented banks contain Special Function Registers. Some frequently used Special Function Registers from one bank are mirrored in another bank for code reduction and quicker access.
