PIC12C5XX

MEMORY ORGANIZATION
PIC12C5XX memory is organized into program mem-
ory and data memory. For devices with more than 512
bytes of program memory, a paging scheme is used.
Program memory pages are accessed using one STA-
TUS register bit. For the PIC12C509, PIC12C509A,
PICCR509A and PIC12CE519 with a data memory
register file of more than 32 registers, a banking
scheme is used. Data memory banks are accessed
using the File Select Register (FSR).
4.1
Program Memory Organization
The PIC12C5XX devices have a 12-bit Program
Counter (PC) capable of addressing a 2K x 12
program memory space.
Only the first 512 x 12 (0000h-01FFh) for the
PIC12C508, PIC12C508A and PIC12CE518 and 1K x
12 (0000h-03FFh) for the PIC12C509, PIC12C509A,
PIC12CR509A, and PIC12CE519 are physically
implemented. Refer to Figure 4-1. Accessing a
location above these boundaries will cause a wrap-
around within the first 512 x 12 space (PIC12C508,
PIC12C508A and PIC12CE518) or 1K x 12 space
(PIC12C509,
PIC12C509A,
PIC12CE519). The effective reset vector is at 000h,
(see Figure 4-1). Location 01FFh (PIC12C508,
PIC12C508A and PIC12CE518) or location 03FFh
(PIC12C509,
PIC12C509A,
PIC12CE519) contains the internal clock oscillator
calibration value. This value should never be
overwritten.
