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 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 incre-
ment 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 0000h, rather than point to
unimplemented address 10000h.
