Signal Description
TIO
Input Tri-
Timer Input/Output—The TIO signal provides an interface to the
or stated timer/event counter module. When the module functions as an
Output
external event counter or is used to measure external pulse width/
signal period, the TIO is an input. When the module functions as a
timer, the TIO is an output, and the signal on the TIO signal is
the timer pulse.
When not used by the timer module, the TIO can be
programmed through the Timer Control/Status Register
(TCSR) to be a General Purpose I/O signal.
TIO is effectively disconnected upon leaving reset.
