5.2
The verify step involves reading back the program
Flash 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 5.1 “Read Program Flash, ID Locations and
Configuration Bits” for implementation details of
reading program Flash.

PIC18F1XK22/LF1XK22
Increment
Pointer
The Table Pointer must be manually set to 200000h
(base address of the ID locations) once the program
Flash has been verified. The post-increment feature of
the table read 4-bit command can not be used to
increment the Table Pointer beyond the program Flash
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
unimplemented address, 010000h.
