Triple Timer
TRIPLE TIMER
Three identical and independent timers are implemented. The three timers can use
internal or external clocking and can interrupt the DSP after a specified number of
events (clocks), or can signal an external device after counting a specific number of
internal events. When a timer port is disabled, it can be used for General Purpose I/O
(GPIO).

GPIO
Input
Timer 0 Schmitt-Trigger Input/Output
When TIO0 is used as an
input, the timer module functions as an external event counter or
measures external pulse width or signal period. When TIO0 is used as
an output, the timer module functions as a timer and TIO0 provides
the timer pulse.
When the TIO0 is not used by the timer module, it can be used for
GPIO.
This pin is electrically disconnected internally during the Stop
processing state.

measures external pulse width or signal period. When TIO1 is used as
an output, the timer module functions as a timer and TIO1 provides
the timer pulse.
When TIO1 is not used by the timer module, it can be used for
GPIO.
This pin is electrically disconnected internally during the Stop
