Description
Audio Channel Status. When "CS_MODE" is set
HIGH, the 23 8-bit bytes of the Audio Channel
Status Block, as defined in AES3-1992, are
available in these registers. Valid in both AES/EBU
and serial audio modes.
When "CS_MODE" is set LOW, the Audio Channel
Status information in the AES/EBU audio outputs
will be replaced with data programmed in these
registers. Valid only in AES/EBU audio mode.
Not used
Audio Channel Status write flag. When set HIGH,
indicates that the audio channel status information
has been written into the Host Interface registers
058h to 06Eh and can be read by the user. Valid
only when "CS_MODE" is set HIGH.
Audio Channel Status request. When set HIGH, the
GS1503B will read and store the Audio Channel
Status information from the audio channel set in
Host Interface register "CH_SEL[2:0]". Valid only
when "CS_MODE" is set HIGH.
Audio Channel Status mode. When set HIGH, the
user can access the embedded Audio Channel
Status information from the Host Interface registers
058h to 06Eh. Valid in both AES/EBU and serial
audio modes.
When set LOW, the Audio Channel Status
information for all audio outputs will be replaced with
data programmed in Host Interface registers 058h -
06Eh. Valid only in AES/EBU audio mode.
Audio Channel Status select. Designates the
embedded audio channel from which the Audio
Channel Status information will be demultiplexed.
The setting 000b represent audio channel 1,
through to 111b for channel 8. Valid only when
"CS_MODE" is set HIGH.
Audio group 4 data packet detect. When set HIGH,
audio data packets with group 4 DID have been
detected in the incoming Chroma video data stream.
NOTE: Once this bit has been set, it will remain set
until a device reset is performed.
Audio group 3 data packet detect. When set HIGH,
audio data packets with group 3 DID have been
detected in the incoming Chroma video data stream.
NOTE: Once this bit has been set, it will remain set
until a device reset is performed.
