MSB First, Right-Justified Serial Interface Format—Monaural ADC Mode, B Left Input
Selected
The monaural output mode for the MSB first, right-justified serial interface format is for 16, 18, 20, and 24 bits with
the following bits in the analog control register set as shown:
Bit 7 (ADM) is set to 1.
Bit 6 (LRB) is cleared to 0.
Bit 1 (INP) is set to 1.
Figure 2–4 shows the following characteristics of this protocol:
Left channel is transmitted when LRCLK is either high or low.
The SDIN(s) (recorded) data is justified to the trailing edge of the LRCLK.
The SDOUT(s) MSB (playback) data is transmitted at the same time as LRCLK edge and captured at the
next rising edge of SCLK.
If LRCLK phase changes by more than 10MCLK, the codec automatically resets.
