The four-wire digital audio interface for the PCM3006 comprises LRCIN (pin 10), BCKIN (pin 11), DIN (pin 15),
and DOUT (pin 12). The PCM3006 accepts 16-bit MSB-first, right-justified format for the DAC and 16-bit
MSB-first, left-justified format for the ADC. The PCM3006 can accept 32, 48, or 64 bit clocks (BCKIN) in one
clock of LRCIN. Figure 32 and Figure 33 illustrate audio data input/output format and timing.
