Table 2-14 Timer Signal
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 D 0—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 5 V tolerant.
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.
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 5 V tolerant.
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 5 V tolerant.
