Writing data to EEPROM is enabled by setting EKEY [7:0] to “A5H”.
Since 51H of 5CH of EEPROM correspond to 11H to 1CH of registers, please refer to the details of a
register function.
*The bit position in 51H, 53H, 55H and 57H of EEPROM do not correspond to the bit positions in 11H,
13H, 15H and 17H of registers.
