FAN 3 input value if FANINC3 sets to 1. Return ‘1’, the pin
18 status is logic high signal. Read ‘0’, pin18 is logic low
signal.
FAN 2 input value if FANINC2 sets to 1. Return ‘1’, the pin
19 status is logic high signal. Read ‘0’, pin19 is logic low
signal.
FAN 1 input value if FANINC1 sets to 1. Return ‘1’, the pin
20 status is logic high signal. Read ‘0’, pin20 is logic low
signal.

Tolerance of Fan 3 Target Speed Count. Only for Fan
Speed Cruise mode.
In Thermal Cruise mode, PWM duty will be 0 if it decreases
to under this value. This register should be written a non-
zero minimum PWM stop duty cycle.
