Program Memory Organization
The enhanced mid-range core has a 15-bit program
counter capable of addressing a 32K x 14 program
memory space.
Table 3-1 shows the memory sizes
implemented
for
the
PIC16(L)F1526/27
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
