3.1 User ID Location
A user may store identification information (user ID) in
four designated locations. The user ID locations are
mapped to 8000h-8003h. 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 Device ID
The device ID word is located at 8006h. This location is
read-only and cannot be erased or modified.
Note: MPLAB
®
IDE only displays the 7 Least
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.

Legend: P = Programmable bit U = Unimplemented bit, read as ‘0’
R = Readable bit W = Writable bit ‘0’ = Bit is cleared
-n = Value at POR ‘1’ = Bit is set x = Bit is unknown
bit 13-5 DEV<8:0>: Device ID bits
These bits are used to identify the part number.
bit 4-0 REV<4:0>: Revision ID bits
These bits are used to identify the revision.
Note 1: This location cannot be written.
