3.1
A user may store identification information (user ID) in
four designated locations. The user ID locations are
mapped to 2000h-2003h. Each location is 14 bits in
length. Code protection has no effect on these memory
locations. Each location may be read with code
protection enabled or disabled.
3.2
The device ID word for the PIC16F/LF720 and the
PIC16F/LF721 is located at 2006h. This location
cannot be erased or modified.

MPLAB
Significant bits (LSb) of each user ID
location, the upper bits are not read. It is
recommended that only the 7 LSbs be
used if MPLAB IDE is the primary tool
used to read these addresses.
