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.
Not used.
Audio mute enable. Same functionality as the MUTE pin. When set
HIGH, the demultiplexed audio and extended packet data are forced
to zero.
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.
Not used.
Designates the 8 LSBs of the arbitrary data packet DID word. The 2
MSBs are internally generated. “PKTID[7]” is the MSB and “PKTID[0]”
is the LSB.
Video/audio delay mode. “BUFSEL[1]” is the MSB and “BUFSEL[0]” is
the LSB. See Table 13 .
AES/EBU CRC select. When set HIGH, the C bit (channel status
information) of each audio sample contains CRC information as
defined in the AES3-1992 standard.
Not used.
Not used.
Sample error. Incorrect number of audio samples detected. 8008
audio samples (48kHz) in 5 video frames for a 525 line video format.
1920 audio samples (48kHz) in 1 video frame for a 625 line video
format.
Audio channel 1/2 CRC error.
Audio channel 3/4 CRC error.
Audio packet DBN error. A DBN discontinuity was detected.
Audio packet DC error. The number of UDW indicated does not match
the number of words found in the data packet.
Not used.
Audio packet inversion bit error. An incorrect bit 9 inversion of bit 8
was detected in the audio packet.
Not used.
Audio control packet DBN error. A DBN discontinuity was detected.
NOTE: When a DBN discontinuity is detected, the VFLA/B pins remain
valid (LOW).
Audio control packet DC error. The number of UDW indicated does not
match the number of words found in the audio control packet.
Not used.
Audio control packet inversion bit error. An incorrect bit 9 inversion of
bit 8 was detected in the audio control packet.
Not used.
Extended audio packet inversion bit error. An incorrect bit 9 inversion
of bit 8 was detected in the extended audio packet.
