2.0
MEMORY ORGANIZATION
2.1
Program Memory Organization
The PIC16F882/883/884/886/887 has a 13-bit program
counter capable of addressing a 2K x 14 (0000h-07FFh)
for the PIC16F882, 4K x 14 (0000h-0FFFh) for the
PIC16F883/PIC16F884, and 8K x 14 (0000h-1FFFh) for
the PIC16F886/PIC16F887 program memory space.
Accessing a location above these boundaries will cause
a wrap-around within the first 8K x 14 space. The Reset
vector is at 0000h and the interrupt vector is at 0004h
(see Figures 2-2 and 2-3).
