Signal Description
GPIO
Digital Audio Data Output—This signal is an audio and non-
Disconnected 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.
