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.
