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 VDD through a pull-up resistor in order to ensure a stable logic level
at this input.
Internal Pull down resistor.
This input is 5 V tolerant.
