be ‘set’ in order to use variable PCM playback or capture rates. The VRA bit also serves as
a powerdown for the DAC and ADC SRC blocks. Clearing VRA will reset the PCM Front DAC
Rate Register (Index 2Ch) and the PCM L/R ADC Rate Register (Index 32h) to their default
values. The SRC data path is flushed and the Slot Request bits for the currently active DAC
slots will be fixed at ‘0’.
