4.1 Program Memory Organization

The PIC16C7X family has a 13-bit program counter

capable of addressing an 8K x 14 program memory

space. The amount of program memory available to

each device is listed below:

For those devices with less than 8K 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.
