Bit 7： Disable power-on abnormal the monitor voltage including V-Core A and +3.3V. If these voltage
Bit 6： Reserved.
Bit 5： FAN 3 output value if FANINC3 sets to 0. Write 1, then pin 18 always generate logic high sig-
Bit 4： FAN 3 Input Control. Set to 1, pin 18 acts as FAN clock input, which is default value. Set to 0,
Bit 3： FAN 2 output value if FANINC2 sets to 0. Write 1, then pin 19 always generate logic high sig-
Bit 2： FAN 2 Input Control. Set to 1, pin 19 acts as FAN clock input, which is default value. Set to 0,
Bit 1： FAN 1 output value if FANINC1 sets to 0. Write 1, then pin 20 always generate logic high sig-
Bit 0： FAN 1 Input Control. Set to 1, pin 20 acts as FAN clock input, which is default value. Set to 0,
exceed the limit value, the pin （Open Drain） of BEEP will drives 300Hz and 600Hz frquency
signal. Write 1, the frequency will be disabled. Default is 0. After power on, the system should
set 1 to this bit to 1 in order to disable BEEP.
