Fan speed control PWM output. By default it’s high.
The power of this pin is supplied by VSB 5V.
FAN_OUT7
OUT12
CASE OPEN detection. An active high input from an
external device when case is Intruded. This signal
can be latched in external circuit which power is
supplied by VBAT, even if W83792D is power off.
