The ID locations are programmed much like the code
memory. The single panel that will be written will auto-
matically be enabled, based on the value of the Table
Pointer. The ID registers are mapped in addresses
200000h through 200007h. These locations read out
normally, even after code protection.

Table 3-6 demonstrates the code sequence required to
write the ID locations.
The Table Pointer must be manually set to 200000h
(base address of the ID locations). The post-increment
feature of the table read 4-bit command may not be
used to increment the Table Pointer to 200000h. The
post-increment feature may then be used to increment
to 200001h, 200002h, etc.
