7.5.3

WRITE VERIFY

Depending on the application, good programming
practice may dictate that the value written to the
memory should be verified against the original value.
This should be used in applications where excessive
writes can stress bits near the specification limit.

7.5.4

UNEXPECTED TERMINATION OF 
WRITE OPERATION

If a write is terminated by an unplanned event, such as
loss of power or an unexpected Reset, the memory
location just programmed should be verified and repro-
grammed if needed. If the write operation is interrupted
by a MCLR Reset, or a WDT time-out Reset during nor-
mal operation, the user can check the WRERR bit and
rewrite the location(s) as needed

program memory.
