ADC_
ADC overflow. Indicates the overrange status in the corresponding signal path. Rising-edge state transitions may cause an
OVFL
interrupt, depending on the programming of the associated interrupt mask bit.
0 No digital clipping has occurred in the data path of the respective signal source.
1 Digital clipping has occurred in the data path of the respective signal source.

EQ_
Digital equalizer biquad overflow. Indicates the overrange status in the individual biquads in the equalizer data path.
BIQUAD_
Rising-edge state transitions may cause an interrupt, depending on the programming of the associated interrupt mask bit.
OVFL
0 No digital clipping occurred in one of the individual biquads in the equalizer data path
