Figure 21 Right Justified Audio Interface (assuming n-bit word length)
In I²S mode, the MSB is available on the second rising edge of BCLK following a FRAME transition.
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 22 I²S Audio Interface (assuming n-bit word length)
In DSP/PCM mode, the left channel MSB is available on either the 1^st (mode B) or 2^nd (mode A)
rising edge of BCLK (selectable by FRAMEP) following a rising edge of FRAME. 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.
