10.2
Code protection is controlled using the CP bit in
Configuration Word 1. When code protection is
enabled, all program memory locations (0000h-7FFFh)
read as all ‘0’. Further programming is disabled for the
program memory (0000h-7FFFh).
Data memory is protected with its own Code-Protect bit
(CPD). When data code protection is enabled (CPD = 0),
all data memory locations read as ‘0’. Further
programming is disabled for the data memory. Data
memory can still be programmed and read during
program execution.
The user ID locations and Configuration Words can be
programmed and read out regardless of the code
protection settings.
10.3
Four memory locations (8000h-8003h) are designated
as ID locations where the user can store checksum or
other code identification numbers. These locations are
not accessible during normal execution, but are read-
able and writable during Program/Verify mode. Only
the Least Significant 7 bits of the ID locations are
reported
