7.4
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.

Write Verify
7.5
There are conditions when the device may not want to
write to the data EEPROM memory. To protect against
spurious EEPROM writes, various mechanisms have
been built-in. On power-up, the WREN bit is cleared;
also, the Power-up Timer prevents EEPROM write.
The write initiate sequence, and the WREN bit
together, help prevent an accidental write during
brown-out, power glitch or software malfunction.
