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”
reading code memory.

Increment
Pointer
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 the code memory
space. In a 64-Kbyte device, for example, a
post-increment read of address, FFFFh, will wrap the
Table Pointer back to 000000h, rather than point to the
unimplemented address, 010000h.
