■ System Clock and Audio Interface Format for Input Port
The audio interface format is controlled by the IDIF pin. The data format is MSB first in 2's complement.
The SDTI input data is clocked in on a rising edge of the IBICK. The audio interface format of the input
port should be changed while the PDN pin = “L”.
