Note 21: Clipping of the outputs occurs when the VDDPA drops and the following conditions becomes true. If CLASSD_CTRL_REG[CLASSD_CLIP]
is not equal to zero then upon a programmable number of clipping occurrences a CLASSD_INT is generated:
The software can stop clipping by reducing the gain via the GENDSP:
Clipping occurs if
