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

Step 1: Direct access to code memory and enable writes.
Step 2: Load write buffer with 8 bytes and write.

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

Table 3-8 demonstrates the code sequence required to
write the ID locations.
In order to modify the ID locations, refer to the method-
ology described in Section 3.2.1 “Modifying Code
Memory”. As with code memory, the ID locations must
be erased before being modified.
