PIC16F610/616/16HV610/616
2.0 MEMORY ORGANIZATION
2.1 Program Memory Organization
The PIC16F610/616/16HV610/616 has a 13-bit
program counter capable of addressing an 8K x 14
program memory space. Only the first 1K x 14
(0000h-3FF) for the PIC16F610/16HV610 and the first
2K x 14 (0000h-07FFh) for the PIC16F616/16HV616 is
physically implemented. Accessing a location above
these boundaries will cause a wraparound within the
first 1K x 14 space (PIC16F610/16HV610) and 2K x 14
space (PIC16F616/16HV616). The Reset vector is at
0000h and the interrupt vector is at 0004h (see
Figure 2-1).
