In Left Justified mode, the MSB is available on the first rising edge of BCLK following an LRCLK
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 before each LRCLK transition.

In Right Justified mode, the LSB is available on the last rising edge of BCLK before an LRCLK
transition. All other bits are transmitted before (MSB first). Depending on word length, BCLK
frequency and sample rate, there may be unused BCLK cycles after each LRCLK transition.
