3.0
PIC16F5X memory is organized into program memory
and data memory. For the PIC16F57, which has more
than 512 words of program memory, a paging scheme
is used. Program memory pages are accessed using
one or two Status register bits. For the PIC16F57,
which has a data memory register file of more than 32
registers, a banking scheme is used. Data memory
banks are accessed using the File Selection Register
(FSR).
3.1
The PIC16F54 has a 9-bit Program Counter (PC)
capable of addressing a 512 x 12 program memory
space (Figure 3-1). The PIC16F57 has an 11-bit
program counter capable of addressing a 2 x 12
program memory space (Figure 3-2). Accessing a
location above the physically implemented address will
cause a wraparound.
A NOP at the Reset vector location will cause a restart
at location 000h. The Reset vector for the PIC16F54 is
at 1FFh. The Reset vector for the PIC16F57 is at 7FFh.
See Section 3.5 “Program Counter” for additional
information using CALL and GOTO instructions.
