5.5.6 TRS Word Insertion
When TRS_INS bit 0 of Host Interface register 008h is set HIGH, the GS1503B will insert
TRS codes into the video data stream. When set LOW, existing TRS codes will remain in
the output video stream.

5.6 Audio Data Processing
5.6.1 Digital Audio Output Format
The GS1503B has two audio output formats, AES/EBU digital audio output and serial
output, as listed in
two modes. See
•
•
The audio output format is configured using the AM[1:0] external pins or via AM[1:0] bits
1-0 in Host Interface register 010h. To configure the audio output format via the Host
Interface, AM_SEL bit 7 in Host Interface register 010h must be set HIGH. The GS1503B
will default to the AM[1:0] external pin setting.
NOTE: When configured in AES/EBU audio mode, the GS1503B will not output a 48kHz
(fs) word clock at the WCOUTA and WCOUTB pins.
