Read the GPIO3 data on the pin.
Read the GPIO2 data on the pin. If this pin serves as IRQ/SMI#, this
bit always indicates 0, that is, read will return 0.
Read the GPIO1 data on the pin.
Read the GPIO0 data on the pin.

When VT1 temperature is exceed this boundary, FAN1 segment 1
speed count registers(INDEX A4h, A5h) will be loaded into FAN1
expect count registers(INDEX 74h,75h).
When VT1 temperature is below this boundary, FAN1 segment 2
speed count registers(INDEX A6h, A7h) will be loaded into FAN1
st
