Normal mode
In normal mode (TRANS pin = “L”), the C, U and V bits are captured (either from the pins, in synchronous mode, or
the control registers, in the asynchronous mode) in the sub frame following the audio data. The V bit is set to zero to
indicate the audio data is suitable for conversion. See
Audio routing mode (transparent mode)
In audio routing mode (transparent mode) (ANS pin = TRANS pin = “H”), the C, U and V bits are captured with the
same sub-frame as the data to which the C, U and V bits correspond. In all DIF modes except 5 and 7, the C, U and V
bits are captured at the first, rising edge of BICK after an LRCK transition. In modes 5 and 7 (I
are captured at the second rising edge. See
