MEMORY ORGANIZATION
Program Memory Organization
The PIC16F91X/946 has a 13-bit program counter
capable of addressing a 4K x 14 program memory
space for the PIC16F913/914 (0000h-0FFFh) and an
8K x 14 program memory space for the PIC16F916/
917 and PIC16F946 (0000h-1FFFh). Accessing a
location above the memory boundaries for the
PIC16F913 and PIC16F914 will cause a wrap around
within the first 4K x 14 space. The Reset vector is at
0000h and the interrupt vector is at 0004h.
