Description
Ch1/2 audio parity error detection. When set
HIGH, an audio parity error has been detected
in the Ch1/2 audio input. Valid only when
AES/EBU audio input format is selected.
Audio Channel Status set. Valid in Serial Audio
Input modes. Used to enter the 23 8-bit bytes
of the Audio Channel Status Block, as defined
in AES3-1992.
NOTE: The CRC byte is generated internally by
the GS1503B.
Audio channel multiplex enable. When set
HIGH, the corresponding audio channel is
multiplexed into the Chroma video data
stream. "CHACT[7]" corresponds to audio input
channel 8 and "CHACT[0]" corresponds to
audio input channel 1. When all bits are set
LOW, no audio data packets will be
multiplexed and the GS1503B will be in bypass
mode.
Cascade select. When set HIGH, the GS1503B
will default to audio groups 3 and 4. When set
LOW, the GS1503B will default to audio groups
1 and 2.
NOTE: The status of the CASCADE external pin
is not updated in this register. The value
programmed in this register is logical OR'd
with the CASCADE external pin setting.
Not used.
Ch5-8 audio mute enable. When set HIGH, the
multiplexed audio packets for audio channels 5
to 8 are forced to zero.
NOTE: The status of the MUTE external pin is
not updated in this register. The value
programmed in this register is logical OR'd
with the MUTE external pin setting.
Ch1-4 audio mute enable. When set HIGH, the
multiplexed audio packets for audio channels 1
to 4 are forced to zero.
NOTE: The status of the MUTE external pin is
not updated in this register. The value
programmed in this register is logical OR'd
with the MUTE external pin setting.
Ch5-8 audio group DID setting. Designates the
audio group DID for audio channels 5 to 8.

or register) is set LOW, the default setting is
audio group 2. When CASCADE is set HIGH, the
default setting is audio group 4.
