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 “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 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 the code memory
space. In a 48-Kbyte device, for example, a post-
increment read of address 0BFFFh will wrap the Table
Pointer back to 0000h, rather than point to
unimplemented address, 0C000h.
