EEUNLK<7:0>: Data EEPROM Unlock Pattern bits

To unlock writes, a 55h must be written first, followed by an AAh, before setting the WR bit of the

EECON1 register. The value written to this register is used to unlock the writes. There are specific

timing requirements on these writes. Refer to Section 23.1.3 “Writing to the Data EEPROM

Memory” for more information.
