Table XXII. Register 0x63 – Enhance Acoustics Reg 2 (Power-On Default = 0x00)
Bit

Name
ACOU3
R/W
*
Read/Write
Description
These bits select the Ramp Rate applied to the PWM3 output. Instead of PWM3 jump-
ing instantaneously to its newly calculated speed, PWM3 will ramp gracefully at the rate
determined by these bits. This effect enhances the acoustics of the fan being driven by the
PWM3 output.

When this bit is 1, Acoustic Enhancement is enabled on PWM3 output.
These bits select the Ramp Rate applied to the PWM2 output. Instead of PWM2
jumping instantaneously to its newly calculated speed, PWM2 will ramp gracefully at the
rate determined by these bits. This effect enhances the acoustics of the fans being driven
by the PWM2 output.
