Audio Clock Input—This is the DAX clock input. When
programmed to use an external clock, this input supplies the DAX
clock. The external clock frequency must be 256, 384, or 512
times the audio sampling frequency (256 × Fs, 384 × Fs or 512 ×
Fs, respectively).
Port D0—When the DAX is configured as GPIO, this signal is
individually programmable as input, output, or internally
disconnected.
The default state after reset is GPIO disconnected.
Internal Pull down resistor.
This input is 5 V tolerant.
Digital Audio Data Output—This signal is an audio and
non-audio output in the form of AES/SPDIF, CP340 and IEC958
data in a biphase mark format.
Port D1—When the DAX is configured as GPIO, this signal is
individually programmable as input, output, or internally
disconnected.
The default state after reset is GPIO disconnected.
Internal Pull down resistor.
This input is 5 V tolerant.
