2.3
The code memory space extends from 0000h to 5FFFh
(24 Kbytes) in three 8-Kbyte panels in PIC18FX539
parts. In PIC18FX439 parts, program space is from
0000h to 2FFFh (12 Kbytes). Addresses 0000h
through 01FFh, however, define a “Boot Block” region
that is treated separately from Panel 1. All code
memory is on-chip.
A user may store identification information (ID) in eight
ID registers. These ID registers are mapped in
addresses 200000h through 200007h. The ID locations
read out normally, even after code protection is applied.
Locations 300001h through 30000Dh are reserved for
the configuration bits. These bits may be set to select
various device options, and are described in
Section 5.0. These configuration bits read out normally,
even after code protected.
Locations 3FFFFEh and 3FFFFFh are reserved for the
device ID bits. These bits may be used by the
programmer to identify what device type is being
programmed, and are described in Section 5.0. These
configuration bits read out normally, even after code
protection.
