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 demultiplexed audio and extended packet data are forced
to zero.

ACTSEL
Audio lock process select. When set HIGH, the GS9023
‘
locks
’
by
detecting the presence of an audio control packet corresponding to
the DID configured in
“
ACID[3:0]
”
and occurring at the expected line
and position as listed in Table 6. When set LOW, the GS9023
‘
locks
’
by
counting the number of audio samples in a frame or multiple frames
and validating the number of samples detected based on the video
standard.

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