MMTLR - Channel Selection for AES Transmitter mono mode
TXOFF - AES3 Transmitter Output Driver Control
AESBP - AES3 bypass mode selection
Default = ‘0’
0 - Normal stereo operation
1 - Output either left or right channel inputs into consecutive subframe outputs (mono
Default = ‘0’
0 - Use channel A CS data for the A subframe and use channel B CS data for the B subframe
1 - Use the same CS data for both the A and B subframe outputs. If MMTLR = 0, use the
