F71869A
Fan 2 control output. It is also a trap pin to select a PWM or
a DAC output, except being an output pin. It defaults to be
a voltage output by pulling down 100k internally. It is set as
a PWM output as connected a 4.7K resistor and pulled
high to 3.3V.

Fan 3 control output. It is also a trap pin to select a PWM or
a DAC output, except being an output pin. It defaults to be
a voltage output by pulling down 100k internally. It is set as
a PWM output as connected a 4.7K resistor and pulled
high to 3.3V. The PWM output frequency can be
programmed to 220Hz for LCD backlight control.
