The PCM Interface may be configured for Mono mode, where only one channel of ADC data is
output. In this mode the interface should be configured for DSP mode. A short or long frame sync is
supported and the MSB is available on either the 1st (mode B) or 2nd (mode A) rising edge of
VXCLK.
Note that when operating in stereo mode the mono Voice DAC always uses the left channel data as
its input.
