4.3
The verify step involves reading back the code memory
space and comparing 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 4.2 for implementation details of reading code
memory.
FIGURE 4-4:
4.4
A configuration address may be read and output on
SDATA 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. The result may then be immediately
compared to the appropriate configuration data in the
programmer’s memory for verification. Refer to
Section 4.2 for implementation details of reading
configuration data.

Preliminary
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 beyond 1FFFFFh.
4.5
A data EEPROM address may be read via a sequence
of core instructions (4-bit command, ‘0000’) and then
output on SDATA via the 4-bit command, ‘0010’ (shift
out data holding register). The result may then be
immediately compared to the appropriate data in the
programmer’s memory for verification. Refer to
Section 4.1 for implementation details of reading data
EEPROM.
