Enhanced Acoustics Register 2 (0x63)
Bits [2:0] (ACOU3), select the ramp rate for PWM outputs
associated with the local temperature channel.
Bits [6:4] (ACOU2), select the ramp rate for PWM outputs
associated with the Remote 2 temperature input.

When Bit 7 of Configuration Register 6 (0x10) = 1, the ramp
rates change to the following values:
Setting the appropriate SLOW bits [2:0] of Configuration
Register 6 (0x10) slows the ramp rate further by a factor of 4.
