MDT10F630
WREN : EEPROM Write Enable Bit.
0 = Inhibits write to the data EEPROM
1 = Allows write cycles
WR : Write Control Bit.
0 = Write cycle to the data EEPROM is complete
1 = Initiates a write cycle. (The bit is cleared by hardware once write is complete.
The WR bit can only be set (not clear) in software.)
RD : Read Control Bit.
0 = Does not initiate an EEPROM read.
1 = Initiates an EEPROM read (read takes once cycle. RD is cleared in hardwave.
The RD bit can only be set (not clear) in software.)
(38). 9DH : EEPROM control register 2.

When write data to the EEPROM must write 55/H to EECON2, and writ AA/H to EECON2 then set WR bit;
the EEPROM can write data inside for write each byte.
