ADO
Output
GPIO Disconnected Digital Audio Data Output—This signal is an audio and non-audio output in
the form of AES/EBU, CP340 and IEC958 data in a biphase mark format.
PD1
Input,
output, or
disconnected
Port D 1—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.
This input is 3.3V tolerant.

Signal Description
TIO0
Input or Output
Input
Timer 0 Schmitt-Trigger Input/Output—When timer 0 functions as an external
event counter or in measurement mode, TIO0 is used as input. When timer 0 functions
in watchdog, timer, or pulse modulation mode, TIO0 is used as output.
The default mode after reset is GPIO input. This can be changed to output or
configured as a timer input/output through the timer 0 control/status register (TCSR0).
If TIO0 is not being used, it is recommended to either define it as GPIO output
immediately at the beginning of operation or leave it defined as GPIO input but
connected to Vcc through a pull-up resistor in order to ensure a stable logic level at this
input.
This input is 3.3V tolerant.

Input
Test Clock—TCK is a test clock input signal used to synchronize the JTAG test logic. It
has an internal pull-up resistor.
This input is 3.3V tolerant.
