4.2
The verify step involves reading back the code memory
space and comparing it against the copy held in the
programmer’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 “Read Code Memory, ID Locations and
Configuration Bits” 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
memory has been verified. The post-increment feature
of the table read 4-bit command may not be used to
increment the Table Pointer to 200000h. After setting
the Table Pointer to 200000h, the post-increment
feature may be used to increment to 200001h,
200002h and so on.

A configuration address may be read and output on
PGD via the 4-bit command, 1001. Configuration data
is read and written in a byte-wise fashion, so it is not
necessary to merge two bytes into a word prior to a
compare.
