DFC0 and DFC1 inputs determine the major data flow options available in hardware mode, according to
Table 3.
Output section master clock input. The frequency must be 256x the output sample rate (Fso).
Audio data serial input pin. This data will be transmitted out the AES3 port.
Serial bit clock for audio data on the SDIN pin.
Word rate clock for the audio data on the SDIN pin. The frequency will be at the output sample rate
(Fso)
Audio data serial output pin. This is also a start-up option pin, and requires a pull-up or pull-down
resistor.
Serial bit clock for audio data on the SDOUT pin.
Word rate clock for the audio data on the SDOUT pin. The frequency will be at the output sample rate
(Fso).
