Miscellaneous Control 2 (2)
HOLD1-0The HOLD bits determine how the received audio sample is affected when a receiver
error occurs.
00 - Hold the last valid audio sample (default)
01 - Replace the current audio sample with 00 (mute)
10 - Do not change the received audio sample
11 - Reserved
RMCKFSelect recovered master clock output pin frequency.
0 - RMCK is equal to 256 * Fsi (default)
1 - RMCK is equal to 128 * Fsi
HOLD1
0 - Data to the SRC is not truncated (default)
1 - Data to the SRC is set according to the AUX field in the incoming data stream
0 - Interpret A and B subframes as two independent channels (normal stereo
1 - Interpret A and B subframes as consecutive samples of one channel of data.
0 - Outputs left channel input into A subframe and right channel input into B subframe
1 - Output either left or right channel inputs into consecutive subframe outputs (mono
0 - Use channel A CS data for the A sub-frame slot and use channel B CS data for the
1 - Use the same CS data for both the A and B sub-frame output slots. If MMTLR = 0, use the
0 - Use left channel input data for consecutive sub-frame outputs (default)
1- Use right channel input data for consecutive sub-frame outputs
