In professional mode, setting TRNPT low selects normal operation & CBL is an output. Setting
TRNPT high, allows the CS8404A to be connected directly to a CS8414. 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.
In professional and consumer modes this pin is the channel status serial input port. In CD mode
this pin inputs the CD subcode frame clock.
In professional and consumer modes, the channel status block output is high for the first 16
bytes of channel status. In CD mode, this pin outputs the subcode bit clock.
Clock input at 128x Fs the sample frequency which defines the transmit timing. In transparent
mode, MCK must be 256x Fs.
RS422 compatible line drivers. Drivers are pulled to low when part is in reset state.
