It inputs a 64 fs bit clock.
This is the word clock pin for the audio interface’s input side.
This is the audio interface’s serial data input pin 3.
If this pin is not used, connect it to a ground.
This is the audio interface’s serial data input pin 2.
If this pin is not used, connect it to a ground.
This is the audio interface’s serial data input pin 1.
If this pin is not used, connect it to a ground.
This is the audio interface’s serial data input pin 0.
Connect digital audio data (various streams or PCM) via IEC60958 to
this pin.
This is the master clock output pin for the audio interface’s output
side.
It outputs the master clock to DIT, DAC, etc.
The highest clock frequency that can be output is 25 MHz.
This is the bit clock I/O pin for the audio interface’s output side.
It inputs or outputs a 64 fs bit clock.
This is the word clock pin for the audio interface’s output side.
This is the audio interface’s serial data output pin 3.
This is the audio interface’s serial data output pin 2.
This is the audio interface’s serial data output pin 1.
This is the audio interface’s serial data output pin 0.
These are external memory address output pins 18 to 0.
If external memory is not used, these pins should be left unconnected.
These are external memory data I/O pins 7 to 0.
If external memory is not used, these pins should be left unconnected.
This is the external memory chip select output pin.
If external memory is not used, this pin should be left unconnected.
This is the external memory output enable output pin.
If external memory is not used, this pin should be left unconnected.
This is the external memory write enable output pin.
If external memory is not used, this pin should be left unconnected.
This is the interrupt request output pin.
