NOTES:
1. In Master mode, the TLV320AIC23B supplies the BCLK, LRCOUT, and LRCIN. In Slave mode, BCLK, LRCOUT, and LRCIN are
supplied to the TLV320AIC23B.
2. In normal mode, BCLK = MCLK/4 for all sample rates except for 88.2 kHz and 96 kHz. For 88.2 kHz and 96 kHz sample rate,
BCLK = MCLK.
3. In USB mode, bit BCLK = MCLK
