Parameter
In professional mode, setting TRNPT low selects normal operation & CBL is an output.
Setting TRNPT high, allows the STA020D to be connected directly to an STA120. In
transparent mode, CBL is an input & MCK must be at 256 Fs. In consumer mode, FC0 and
FC1 are encoded versions of channel status bits 24 and 25. When FC0 and FC1 are both
high, CD mode is selected.
Master Clock. Clock input at 128x the sample frequency which defines the transmit timing.
In trasparent mode MCK must be 256 Fs.
