I
Clip and TRS correction control. When HIGH, the TRS Blanking, ITU-R-601 clipping and TRS
insertion features are enabled.

O
O
TRS error indication. When HIGH, indicates a TRS error in the data stream such as a missing
TRS, an improperly placed TRS, or an incorrect TRS ID word.
Ancillary data indication. When HIGH, indicates that an ANC packet is coming out of the
device. The output is high from the beginning of the first header word to the end of the
checksum word of the ANC packet.
