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).
