Bit 7: Disable power-on abnormal the monitor voltage including V-Core A and +3.3V. If these voltage
exceed the limit value, the pin (Open Drain) of BEEP will drives 300Hz and 600Hz frequency
signal. Write 1, the frequency will be disable. Default 0. After power on, the system should set
1 to this bit to 1 in order to disable BEEP.
Bit 6: BEEP/GPO# Pin Function Select. Write 1 Select GPO# function. Set 0, select BEEP function.
This bit default 0.
Bit 5: FAN 3 output value if FANINC3 sets to 0. Write 1, then pin 4 always generate logic high
signal. Write 0, pin 4 always generates logic low signal. This bit default 0.
Bit 4: FAN 3 Input Control. Set to 1, pin 4 acts as FAN clock input, which is default value. Set to 0,
this pin 4 acts as FAN control signal and the output value of FAN control is set by this register
bit 5. This output pin can connect to power PMOS gate to control FAN ON/OFF.
Bit 3: FAN 2 output value if FANINC2 sets to 0. Write 1, then pin 3 always generate logic high
signal. Write 0, pin 3 always generates logic low signal. This bit default 0.
Bit 2: FAN 2 Input Control. Set to 1, pin 3 acts as FAN clock input, which is default value. Set to 0,
this pin 3 acts as FAN control signal and the output value of FAN control is set by this register
bit 3. This output pin can connect to power NMOS gate to control FAN ON/OFF.
Bit 1: FAN 1 output value if FANINC1 sets to 0. Write 1, then pin 2 always generate logic high
signal. Write 0, pin 2 always generates logic low signal. This bit default 0.
Bit 0: FAN 1 Input Control. Set to 1, pin 2 acts as FAN clock input, which is default value. Set to 0,
this pin 2 acts as FAN control signal and the output value of FAN control is set by this register
bit 1. This output pin can connect to power PMOS gate to control FAN ON/OFF.
