Bit 6: CPUFANOUT1 output mode selection. Set to 0, CPUFANOUT1 pin is as PWM output duty
cycle so that it can drive a logical high or low signal. Set to 1, CPUFANOUT1 pin is as DC
voltage output which can provide analog voltage output. (Default 1)
Bit 5-4: CPUFANOUT1 mode control.
Set 00, CPUFANOUT1 is as Manual Mode. (Default).
Set 01, CPUFANOUT1 is as Thermal Cruise Mode.
Set 10, CPUFANOUT1 is as Fan Speed Cruise Mode.
Set 11, CPUFANOUT1 is SMART FAN^TM III Mode.
(1)When at Thermal Cruise mode or SMART FAN^TM III mode:
Bit3-0: Tolerance of select temperature source Target Temperature.
(2)When at Fan Speed Cruise mode:
Bit3-0: Tolerance of CPUFANIN1 Target Speed.
