Triggered One-Shot Mode Time-Out Period(s)
TRIGGERED ONE-SHOT Mode
In TRIGGERED ONE-SHOT mode, the timer operates as follows:
1. The timer is non-active until a trigger is received. The timer trigger is taken from the
2. Following the trigger event, the timer counts system clocks up to the 16-bit Reload
3. After reaching the Reload value, the timer outputs a pulse on the timer output pin,
4. The timer now idles until the next trigger event. Trigger events, which occur while the

initiate operation:
1. Write to the timer control registers to:
2. Write to the timer high and low byte registers to set the starting count value.
3. Write to the timer reload high and low byte registers to set the reload value.
4. Enable the timer interrupt, if required and set the timer interrupt priority by writing to
