DAC1 Volume Control Registers (DAC1x_VOL)
These registers manage the output signal volume for DAC1, Left and Right respectively.
-
The MSB, bit D7, of each register is the mute bit. When this bit is set, the output is silent.
-
There are 128 gain selections from 0 dB to -95.25 dB. The step size is 0.75 dB.
