7.3.2
To write a block of data EEPROM, write to all sixteen
latches first, then set the NVMCON register and
program the block.
EXAMPLE 7-5:
7.4
Depending on the application, good programming
practice may dictate that the value written to the mem-
ory 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
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.
