Description
0
Min 1
R/W
When the ADT7462 is in automatic fan control mode, this bit defines whether PWM1 is off (0% duty cycle) or at minimum
PWM1 duty cycle when the controlling temperature is below its TMIN hysteresis value.
0 = 0% duty cycle below TMIN hysteresis (default); 1 = minimum PWM1 duty cycle below TMIN hysteresis.

Min 2
R/W
When the ADT7462 is in automatic fan control mode, this bit defines whether PWM2 is off (0% duty cycle) or at minimum
PWM2 duty cycle when the controlling temperature is below its TMIN hysteresis value.
0 = 0% duty cycle below TMIN hysteresis (default); 1 = minimum PWM2 duty cycle below TMIN hysteresis.
