Inputs ADC and I
SPDIF
Input SPDIF to output I
Input SPDIF to output I
and WS being master; the clocks for
this are recovered from the SPDIF
input signal
The rest of the clocks are generated by
the crystal oscillator
SPDIF input channel status bits (two
times 40) can be read
SPDIF output channel status bits (two
times 40) setting
Possibility to process input SPDIF, via
I
then to outputs DAC or SPDIF.
Inputs ADC and SPDIF to outputs DAC

Possibility to process inputs ADC or
SPDIF, via I
DSP and then to output SPDIF.
