2.1 User ID Location

The user may store identification information (User ID) in 32 designated locations. The User ID locations are mapped to addresses 20 0000h-20 003Fh. Each location is 16 bits in length. Code protection has no effect on these memory locations. Each location may be read with code protection enabled or disabled.

If the ICSP interface of the device has been disabled using the Programming and Debugging Interface Disable (PDID) feature on this device (ICSPDIS = 0), the User ID information stored in these memory locations will no longer be accessible and can no longer be read.
