Right ADC Channel Output Valid Flag. Set to “1” if slot 3 (or 19) contains valid right ADC capture data.
Left ADC Channel Output Valid Flag. Set to “1” if slot 2 (or 18) contains valid left ADC capture data.
DAC2 Input Request Flag. Set to “1” if DAC2 is enabled and its four word stereo input buffer is not full.
DAC1 Input Request Flag. Set to “1” if DAC1 is enabled and its four word stereo input buffer is not full.
Reserved for future expansion. Read back as “0.” Should be ignored to ensure future compatibility.
