(1)If SYSFANOUT be programmed as PWM output (Bank0 Index 04h.bit0 is 0)
Bit 7-0: SYSFANOUT PWM Duty Cycle. Write FFh, SYSFANOUT is always logical High which means
Note. XXh: PWM Duty Cycle output percentage is (XX/256*100%) during one cycle.
(2)If SYSFANOUT be programmed as DC Voltage output (Bank0 Index 04h.bit0 is 1)
Bit 7-2: SYSFANOUT voltage control.
Bit 1-0: Reserved.
