2.1 Program Memory Organization
The PIC12F629/675 devices have a 13-bit program counter capable of addressing an 8K x 14 program memory space. Only the first 1K x 14 (0000h-03FFh) for the PIC12F629/675 devices is physically implemented.
Accessing a location above these boundaries will cause a wrap-around within the first 1K x 14 space. The Reset vector is at 0000h and the interrupt vector is at 0004h (see Figure 2-1).
