MMTLR
MMT - Select AES3 transmitter mono or stereo operation
Default = ‘0’
0 - Normal stereo operation
1 - Output either left or right channel inputs into consecutive subframe outputs (mono
mode, left or right is determined by MMTLR bit)
MMTCS - Select A or B channel status data to transmit in mono mode
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
left channel CS data. If MMTLR = 1, use the right channel CS data.
MMTLR - Channel Selection for AES Transmitter mono mode
Default = ‘0’
0 - Use left channel input data for consecutive subframe outputs
1- Use right channel input data for consecutive subframe outputs

The Data Flow Control register configures the flow of audio data. The output data should be muted prior to changing
bits in this register to avoid transients.
TXOFF - AES3 Transmitter Output Driver Control
Default = ‘0
0 - AES3 transmitter output pin drivers normal operation
1 - AES3 transmitter output pin drivers drive to 0 V.
AESBP - AES3 bypass mode selection
Default = ‘0’
0 - Normal operation
1 - Connect the AES3 transmitter driver input directly to the RXP pin, which becomes a normal TTL
threshold digital input.
