DS41417A-page 15 PIC16F/LF722A/723A 2.0 MEMORY ORGANIZATION 2.1 Program Memory Organization The PIC16F/LF722A/723A has a 13-bit program counter capable of addressing a 2K x 14 program memory space for the PIC16F/LF722A (0000h-07FFh) and a 4K x 14 program memory space for the PIC16F/LF723A (0000h-0FFFh). Accessing a location above the memory boundaries for the PIC16F/LF722A will cause a wrap-around within the first 2K x 14 program memory space. Accessing a location above the memory boundaries for the PIC16F/LF723A will cause a wrap-around within the first 4K x 14 program memory space. The Reset vector is at 0000h and the interrupt vector is at 0004h.
