I2S Timing
I2S timing uses an LRCLK to define when the data being transmitted is for the left channel or the right channel.
The LRCLK is low for the left channel and high for the right channel. A bit clock running at 48 or 64 times Fs
is used to clock in the data. There is a delay of one bit clock from the time the LRCLK signal changes state
to the first bit of data on the data lines. The data is written MSB first and is valid on the rising edge of the bit
clock. The TAS5036B masks unused trailing data bit positions. Master mode only supports a 64 times Fs bit
clock.
