EEPROM Function
The EM65570 provides EEPROM function to set the LCD operating voltage Vop. It can
also select the EEPROM operating mode. In EEPROM select register (Bank 5[AH]),
use (M1, M0) to select the operating mode for EEPROM.
You can get the Vop calibration offset voltage by setting Vop calibration offset register
(Bank 5[BH &EH]).
