MEMORY ORGANIZATION

There are two memory blocks in each of these PIC®

microcontroller devices. Each block (Program Memory

and Data Memory) has its own bus so that concurrent

access can occur.

Additional information on device memory may be found

in the PIC® Mid-Range Reference Manual, (DS33023).

2.1

Program Memory Organization

The PIC16C712/716 has a 13-bit Program Counter

(PC) capable of addressing an 8K x 14 program mem-

ory space. PIC16C712 has 1K x 14 words of program

memory and PIC16C716 has 2K x 14 words of program

memory. Accessing a location above the physically

implemented address will cause a wraparound.

The Reset vector is at 0000h and the interrupt vector is

at 0004h.
