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.
