Input
Timer 2 Schmitt-Trigger Input/Output
Ñ
When Timer 2 functions as an external event
counter or in measurement mode, TIO2 is
used as input. When timer 2 functions in
watchdog, timer, or pulse modulation mode,
TIO2 is used as output.
This signal is driven by a weak keeper after
reset.
The default mode after reset is GPIO input.
This can be changed to output or configured
as a timer input/output through the timer 2
control/status register (TCSR2).
