3.8
There are conditions when the device should not write
to the data EEPROM memory. To protect against
spurious EEPROM writes, various mechanisms have
been built-in. On power-up, WREN is cleared. Also, the
Power-up
EEPROM write.
The write initiate sequence and the WREN bit together
help prevent an accidental write during brown-out,
power glitch or software malfunction.

3.9
When the data EEPROM is code-protected, the micro-
controller can read and write to the EEPROM normally.
However, all external access to the EEPROM is
disabled. External write access to the program memory
is also disabled.
When program memory is code-protected, the micro-
controller can read and write to program memory
normally as well as execute instructions. Writes by the
device may be selectively inhibited to regions of
the memory depending on the setting of bits,
