Bit 7: Fan3 divisor Bit 2.
Bit 6: Fan2 divisor Bit 2.
Bit 5: Fan1 divisor Bit 2.
Bit 4: Reserve.
Bit 3: Temperature sensor 3 select into thermal diode such as Pentium II CPU supported. Set to 1,
select bipolar sensor. Set to 0, select thermistor sensor.
Bit 2: Sensor 2 type selection. Defined as DIODES3 described in the bit 3.
Bit 1: Sensor 1 type selection. Defined as DIODES2 described in the bit 3.
Bit 0: Set to 1, enable battery voltage monitor. Set to 0, disable battery voltage monitor. If enable this
bit, the monitor value is value after one monitor cycle. Note that the monitor cycle time is at
least 300ms for W83782D.
