The verify step involves reading back the code memory
space and comparing it against the copy held in the
programmer’s buffer. The Configuration words are
verified with the rest of the code.
The verify process is illustrated in
word of the instruction is read, and then the lower byte
of the upper word is read and compared against the
instruction stored in the programmer’s buffer. Refer to
Section 3.8
implementation details of reading code memory.

Verify Code Memory and
Configuration Bits
Because the Configuration bytes include
the device code protection bit, code mem-
ory should be verified immediately after
writing, if the code protection is to be
enabled. This is because the device will
not be readable or verifiable if a device
Reset occurs after the code-protect bit
has been cleared.

Exiting Program/Verify mode is done by removing V
from MCLR, as illustrated in
requirement for exit is that an interval P16 should
elapse between the last clock and program signals on
PGECx and PGEDx before removing V
