6.5.3
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.
6.5.4
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-

by a MCLR Reset or a WDT time-out Reset during
normal operation, the user can check the WRERR bit
and rewrite the location(s) as needed.
