Microchip Technology 

PIC16F913/914/916/917/946

2.0 MEMORY ORGANIZATION

2.1 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.
