... Program Memory Organization The PIC16CXX has a 13-bit program counter capable of addressing program memory space. For the PIC16C84, only the first (0000h-03FFh) are physically implemented (Figure 4-1). Accessing a loca- tion above the physically implemented address will cause a wraparound. For example, locations 20h, 420h, 820h, C20h, 1020h, 1420h, 1820h, and 1C20h will be the same instruction ...
