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.

Memory”. As with code memory, the ID locations must
be erased before being modified.
