VOLUME CONFIGURATION REGISTER (0x0E)
Bits Volume slew rate (Used to control volume change and MUTE ramp rates). These bits control the
D2–D0: number of steps in a volume ramp.Volume steps occur at a rate that depends on the sample rate of
the I2S data as follows
Sample Rate (KHz) Approximate Ramp Rate
8/16/32 125 us/step
11.025/22.05/44.1 90.7 us/step
12/24/48 83.3 us/step
