Miscellaneous Control 2 (02h)

TRUNC

Determines whether the word length is set according to the incoming Channel Status data

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

HOLD[1:0]

The 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

RMCKF

Select recovered master clock output pin frequency.

0 - RMCK is equal to 256 * Fsi (default)

1 - RMCK is equal to 128 * Fsi

MMR

Select AES3 receiver mono or stereo operation

0 - Interpret A and B subframes as two independent channels (normal stereo operation, default)

1 - Interpret A and B subframes as consecutive samples of one channel of data.This data is

duplicated to both left and right parallel outputs of the AES receiver block. The input sample

rate (Fsi) is doubled compared to MMR=0

MMT

Select AES3 transmitter mono or stereo operation

0 - Outputs left channel input into A subframe and right channel input into B subframe (normal

stereo operation, default).

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

0 - Use channel A CS data for the A sub-frame slot and use channel B CS data for the B sub-

frame slot (default)

1 - Use the same CS data for both the A and B sub-frame output slots. 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

0 - Use left channel input data for consecutive sub-frame outputs (default)

1 - Use right channel input data for consecutive sub-frame outputs
