CDB5368
In TDM mode, SDOUT_SEL1 and SDOUT_SEL 0 extract two stereo pairs from the CS5368 TDM stream,
convert the data to Left-Justified PCM format and send the data to the CS8406 data input pin.
0x00 TDM Pair 1 (Channel 1, 2)
0x01 TDM Pair 2 (Channel 3, 4)
0x10 TDM Pair 3 (Channel 5, 6)
0x11 TDM Pair 4 (Channel 7, 8)
In PCM mode, SDOUT_SEL1 and SDOUT_SEL 0 select which SDOUT pin of the CS5368 is sent to the
CS8406.
0x00 SDOUT1 (Channel 1, 2)
0x01 SDOUT2 (Channel 3, 4)
0x10 SDOUT3 (Channel 5, 6)
0x11 SDOUT4 (Channel 7, 8)
TDM2PCM/PCM selects the clock source for the CS8406.
0x00 8406 Clock Source is CS5368
0x01 8406 Clock Source is the FPGA TDM2PCM engine
