4.0
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
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.
