TIMING DIAGRAMS
Input Timing Examples (DI, BCKI, LRCI)
Audio data input timing (rear-packed 16-bit word, IFM1 = LOW, IFM2 = LOW)
Audio data input timing (rear-packed 20-bit word, IFM1 = LOW, IFM2 = HIGH)
Audio data input timing (front-packed 20-bit word, IFM1 = HIGH, IFM2 = LOW)
All data bits after the LSB (20th bit) are ignored. Accordingly, more than 20 BCKI cycles are required.
