Register Settings
2.6.7 Audio Data Packet DID Setting
The audio group DID for audio output channels 1 to 4
(AOUT1/2 and AOUT3/4) is set in DATAIDA[1:0] bits 1-0 of
Host Interface register 014h. The audio group DID for audio
output channels 5 to 8 (AOUT5/6 and AOUT7/8) is set in
DATAIDB[1:0] bits 3-2 of Host Interface register 014h. Table
12 shows the 2-bit Host Interface setting for the
corresponding audio group DID.
When CASCADE is set LOW (external pin or register), the
GS1503 will default to audio groups 1 and 2, where AOUT1/
2 and AOUT3/4 will be demultiplexed from audio data
packets with group 1 DID, and AOUT5/6 and AOUT7/8 will
be demultiplexed from audio data packets with group 2
DID.
Register Settings (CASCADE set LOW)
When CASCADE is set HIGH (external pin or register), the
GS1503 will default to audio groups 3 and 4, where
AOUT1/2 and AOUT3/4 will be demultiplexed from audio
data packets with group 3 DID, and AOUT5/6 and AOUT7/8
will be demultiplexed from audio data packets with group 4
DID.
