In Thermal Cruise mode, PWM duty will increase
from 0 to this register value to provide a minimum
duty cycle to turn on the fan. This register should be
written a fan start-up duty cycle.
In Thermal Cruise mode, PWM duty will increase
from 0 to this register value to provide a minimum
duty cycle to turn on the fan. This register should be
written a fan start-up duty cycle.
In Thermal Cruise mode, this register determines the
time of which PWM duty is from stop duty cycle to 0
duty cycle. The unit of this register is 0.1 second. The
default value is 6 seconds.
