In Right Justified mode, the LSB is available on the last rising edge of SCLK before a LRCLK transi-
tion. All other bits are transmitted in order. The LRCLK signal is high when left channel data is pres-
ent and low when right channel data is present.
In I
The other bits up to the LSB are then transmitted in order.
