This bit is set when the Audio Bitstream DAC is ready to receive a new data in SDR.
This bit is cleared when the Audio Bitstream DAC is not ready to receive a new data in SDR.
This bit is set when at least one Audio Bitstream DAC Underrun has occurred since the last time this bit was cleared (by reset or
by writing in ICR).
This bit is cleared when no Audio Bitstream DAC Underrun has occurred since the last time this bit was cleared (by reset or by
writing in ICR).
