Bit 7~4: Reserved.
Bit 3: FAN 2 output value if FANINC2 sets to 0. Write 1, then pin 113 always generate logic high
signal. Write 0, pin 113 always generates logic low signal. This bit default 0.
Bit 2: FAN 2 Input Control. Set to 1, pin 113 acts as FAN clock input, which is default value. Set to 0,
this pin 113 acts as FAN control signal and the output value of FAN control is set by this register
bit 3.
Bit 1: FAN 1 output value if FANINC1 sets to 0. Write 1, then pin 114 always generate logic high
signal. Write 0, pin 114 always generates logic low signal. This bit default 0.
Bit 0: FAN 1 Input Control. Set to 1, pin 114 acts as FAN clock input, which is default value. Set to 0,
this pin 114 acts as FAN control signal and the output value of FAN control is set by this register
