4.2
The verify step involves reading back the code memory
space and comparing against the copy held in the pro-
grammer’s buffer. Memory reads occur a single byte at
a time, so two bytes must be read to compare against
the word in the programmer’s buffer. Refer to
Section 4.1 for implementation details of reading code
memory.

The Table Pointer must be manually set to 200000h
(base address of the ID locations) once the code mem-
ory has been verified. The post-increment feature of
the Table Read 4-bit command may not be used to
increment the Table Pointer beyond 1FFFFFh.
