[*] When writing APC_FF data into EEPROM, be noted that AD code data (EEPROM address equivalent
where APC_FF data is stored) becomes larger when detected temperature of the On-chip temperature
sensor is higher (The relation of detected temperature of the On-chip sensor and output voltage is reversed).
4.5 Current Monitor
A current multiplied by 0.012 factor of the I-DAC2 output current (Sink current) is output as Sourcing current
on BIASMON-pin.
