DSP Mode Timing

DSP mode timing uses an LRCLK to define when data is to be transmitted for both channels. A bit clock running

at 64

× Fs is used to clock in the data. The first bit of the left channel data appears on the data lines following

the LRCLK transition. The data is written MSB first and is valid on the rising edge of the bit clock. The TAS5036

masks unused trailing data bit positions.
