Code Protection
If the code protection bit(s) have not been
programmed, the on-chip program memory can be
read out using ICSP™ for verification purposes.

User ID
Four memory locations (2000h-2003h) 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 when using MPLAB IDE. See the
“PIC16F72X/PIC16LF72X Memory Programming
Specification” (DS41332) for more information.

The entire Flash program memory will be
erased when the code protection is turned
off. See the “PIC16F72X/PIC16LF72X
