decreases to under this value. This register should be
written a non-zero minimum PWM stop duty cycle.
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.
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.
In Thermal Cruise mode, PWM duty will be 0 if it
