Table 4-24: Register Settings (CASCADE set LOW)
When CASCADE is set HIGH (external pin or register), the GS1503B will default to audio
groups 3 and 4, where AIN1/2 and AIN3/4 will be multiplexed with audio group 3 DID,
and AIN5/6 and AIN7/8 with audio group 4 DID.
Table 4-25: Register Settings (CASCADE set HIGH)
4.7.3 Audio Channel Multiplex Enable
Multiplexing of individual audio channels is enabled using the CHACT[7:0] bits 7-0 of
Host Interface register 013h. When set HIGH, the corresponding audio channel is
multiplexed into the audio data packet in the Chroma video data stream. CHACT7
corresponds to audio input channel 8 and CHACT0 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.
