Table 40. Register 0x62—Enhanced Acoustics Register 1 (Power-On Default = 0x00)
Bit
Name
R/W1
Description
[2:0]
ACOU
R/W
These bits select the ramp rate applied to the PWM1 output. Instead of PWM1 jumping instantaneously to
its newly calculated speed, PWM1 ramps gradually at the rate determined by these bits. This feature
enhances the acoustics of the fan being driven by the PWM1 output.

EN1
R/W
When this bit is 1, acoustic enhancement is enabled on PWM1 output.
[4]
SYNC
R/W
SYNC = 1 synchronizes fan speed measurements on TACH2, TACH3, and TACH4 to PWM3. This allows up to
three fans to be driven from PWM3 output and their speeds to be measured.
SYNC = 0 synchronizes only TACH3 and TACH4 to PWM3 output.
[5]
MIN1
R/W
When the ADT7473/ADT7473-1 is in automatic fan control mode, this bit defines whether PWM1 is off (0%
duty cycle) or at PWM1 minimum duty cycle when the controlling temperature is below its TMIN – hysteresis
value.
0 = 0% duty cycle below TMIN hysteresis.
1 = PWM1 minimum duty cycle below TMIN hysteresis.
[6]
MIN2
R/W
When the ADT7473/ADT7473-1 is in automatic fan speed control mode, this bit defines whether PWM2 is off
(0% duty cycle) or at PWM2 minimum duty cycle when the controlling temperature is below its TMIN
hysteresis value.
0 = 0% duty cycle below TMIN hysteresis.
1 = PWM 2 minimum duty cycle below TMIN hysteresis.
[7]
MIN3
R/W
When the ADT7473/ADT7473-1 is in automatic fan speed control mode, this bit defines whether PWM3 is off
(0% duty cycle) or at PWM3 minimum duty cycle when the controlling temperature is below its TMIN
hysteresis value.
0 = 0% duty cycle below TMIN hysteresis.
1 = PWM3 minimum duty cycle below TMIN hysteresis.
1 This register becomes read-only when the Configuration Register 1 lock bit is set to 1. Any further attempts to write to this register have no effect.
