MEMORY ORGANIZATION
The PIC12F519 memory is organized into program
memory and data memory (SRAM). The self-writable
portion of the program memory called Flash data mem-
ory, is located at addresses 400h-43Fh. As the device
has more than 512 bytes of program memory, a paging
scheme is used. Program memory pages are accessed
using STATUS register bit, PA0. For the PIC12F519,
with data memory register files of more than 32 regis-
ters, a banking scheme is used. Data memory banks
are accessed using the File Select Register (FSR).
4.1
Program Memory Organization for
the PIC12F519
The PIC12F519 device has an 11-bit Program Counter
(PC) capable of addressing a 2K x 12 program memory
space.
Only the first 1K x 12 (0000h-03FFh) are physically
implemented (see Figure 4-1). Accessing a location
above these boundaries will cause a wrap-around
within the 1K x 12 space. The effective Reset vector
is a 0000h (see Figure 4-1). Location 03FFh contains
the internal clock oscillator calibration value. This
value should never be overwritten.

Address 0000h becomes the effective
Reset vector. Location 03FFh contains
the MOVLW XX internal oscillator
calibration value.
2:
Flash data memory is non-executable.
