4.0
The PIC12F508/509/16F505 memories are organized
into program memory 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 STATUS register bit. For the PIC12F509 and
PIC16F505, with data memory register files of more
than 32 registers, a banking scheme is used. Data
memory banks are accessed using the File Select
Register (FSR).
4.1
The PIC12F508 device has a 10-bit Program Counter
(PC) and PIC12F509 has a 11-bit Program Counter
(PC) capable of addressing a 2K x 12 program memory
space.
Only the first 512 x 12 (0000h-01FFh) for the
PIC12F508, and 1K x 12 (0000h-03FFh) for the
PIC12F509
Figure 4-1). Accessing a location above these
boundaries will cause a wrap-around within the first
512 x 12 space (PIC12F508) or 1K x 12 space
(PIC12F509). The effective Reset vector is a 0000h
(see Figure 4-1). Location 01FFh (PIC12F508) and
location 03FFh (PIC12F509) contain the internal
clock oscillator calibration value. This value should
never be overwritten.
