In I
The other bits up to the LSB are then transmitted in order. Depending on word length, BCLK
frequency and sample rate, there may be unused BCLK cycles between the LSB of one sample
and the MSB of the next.
Figure 34 I
In DSP/PCM mode, the left channel MSB is available on either the 1
rising edge of BCLK (selectable by AIF_LRCLKINV) following a rising edge of LRC. Right channel
data immediately follows left channel data. Depending on word length, BCLK frequency and
sample rate, there may be unused BCLK cycles between the LSB of the right channel data and the
next sample.
In device master mode, the LRC output will resemble the frame pulse shown in Figure 35 and
Figure 36. In device slave mode, Figure 37 and Figure 38, it is possible to use any length of frame
pulse less than 1/fs, providing the falling edge of the frame pulse occurs greater than one BCLK
period before the rising edge of the next frame pulse.

S mode, the MSB is available on the second rising edge of BCLK following a LRCLK transition.
