DS30234D-page 19 PIC16C6X 4.0 MEMORY ORGANIZATION 4.1 Program Memory Organization The PIC16C6X 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.
