, each time slot is 24 bits long and contains the 24bit audio data for the corresponding channel.
In the case of BCK = 128f
, each time slot is 32 bits long and contains the 24bit audio data for the corresponding channel.
The audio data is left justified in the time slot, with the the least significant 8 bits of each time slot being
