ACID[3:0]
Designates the 4 LSBs of the audio control packet DID word. The 6 MSBs are
internally generated.
“
ACID[3]
”
is the MSB and
“
ACID[0]
”
is the LSB.

MUTE
Audio mute enable. Same functionality as the MUTE pin. When set HIGH, the
multiplexed audio and extended data packets are forced to zero.
R/W

AC34/12
Audio control packet channel pair select. When set HIGH, audio control
packet delay data for audio channels 3 and 4 is captured in registers Ah, Bh,
Ch and Dh. When set LOW, audio control packet delay data for audio
channels 1 and 2 is captured in registers #Ah, #Bh, #Ch and #Dh.
R/W

7
CASCADE
Cascade select. When set HIGH, the GS9023 device is part of a cascaded
architecture. New packets are multiplexed into the video signal starting at the
first free location of the HANC space if there is sufficient remaining space to
insert the packet. When set LOW, new packets are multiplexed into the video
signal starting after EAV. Existing ancillary data packets are overwritten and
the remaining ancillary space is cleared.

PKTID[7:0]
Designates the 8 LSBs of the arbitrary data packet DID word. The 2 MSBs
are internally generated.
“

ADERR
Audio data packet multiplexing error. The packet will not be multiplexed
because of insufficient room in the HANC space. Error is cleared when read.

PKTPRTY
Arbitrary data packet parity select. When set HIGH, a parity bit is generated
for every user data word (UDW) of an arbitrary data packet. This overwrites
any data input at the PKT[8] pin.

DELA/B[7:0]
Audio control packet delay. Designates the audio control packet delay data
as specified in the SMPTE 272M standard.
“
DELA
”
corresponds to audio
channels 1 and 2, while
“
DELB
”
corresponds to audio channels 3 and 4.

ACSYNCA/B
Audio control packet synchronization data. Designates the sync mode bits
(asx, asy), as defined in SMPTE 272M (Section 14.5), of channels 1/2 or 3/4
of the audio control packet. The bits are selected by
“
AC34/12

an audio control packet as defined in SMPTE 272 (Section 14.7). When set
HIGH indicates valid audio delay data.
