2.1

Program Memory Organization

The mid-range core has a 13-bit program counter

capable of addressing 8K x 14 program memory space.

This device family only implements up to 512 words of

the 8K program memory space. Table 2-1 shows the

memory sizes implemented for the PIC10(L)F320/322

family. Accessing a location above these boundaries will

cause a wrap-around within the implemented memory

space. The Reset vector is at 0000h and the interrupt

vector is at 0004h (see Figures 2-1, and 2-2).
