Control 2 (2) - Cirrus Logic Crystal CS8427 Series Preliminary Product Information

7.2 Control 2 (2)

7 6
0 HOLD1
HOLD1:HOLD0 - Determine how received audio sample is affected when a receiver error occurs
Default = '00'
00 - Hold the last valid audio sample
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.
Default = '0'
0 - RMCK is equal to 256 * Fsi
1 - RMCK is equal to 128 * Fsi
MMR - Select AES3 receiver mono or stereo operation
Default = '0'
0 - Normal stereo operation
1 - A and B subframes treated as consecutive samples of one channel of data. 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
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
