n C, U, V Serial Ports
Normal mode
In normal mode (TRANS pin = “0”), 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. The V12 pin indicates validity for Channels 1 & 2 and V34 pin
indicates validity for Channels 3 & 4 respectively. See Figure 4 and Figure 5.
Audio routing mode (transparent mode)
In audio routing mode (transparent mode) (ANS pin = TRANS pin = “1”), 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 Figure 6 and Figure 7.
