The ID locations are programmed much like the
program Flash. The ID registers are mapped in
addresses 200000h through 200007h. These locations
read out normally even after code protection.

ID Location Programming
The user only needs to fill the first 8 bytes
of the write buffer in order to write the ID
locations.

NOP - hold PGC high for time P9 and low for time P10.
Advance Information
Table 4-8 demonstrates the code sequence required to
write the ID locations.
In order to modify the ID locations, refer to the
methodology described in Section 4.2.1 “Modifying
Program Flash”. As with program Flash, the ID
locations must be erased before being modified.
