TABLE 11-3: SUMMARY OF REGISTERS ASSOCIATED WITH DATA EEPROM REGISTER 11-6: EECON2: EEPROM CONTROL 2 REGISTER W-0/0 W-0/0 W-0/0 W-0/0 W-0/0 W-0/0 W-0/0 W-0/0 EEPROM Control Register 2 bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ S = Bit can only be set x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets ‘1’ = Bit is set ‘0’ = Bit is cleared bit 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 11.2.2 “Writing to the Data EEPROM Memory” for more information.
