6. Configure the associated GPIO port pin for the timer input alternate function.
7. Write to the timer control register to enable the timer and initiate counting.
In CAPTURE mode, the elapsed time between the timer start and the Capture event can be
calculated using the following equation:
Capture Elapsed Time (s)
COMPARE Mode
In COMPARE mode, the timer counts up to 16-bit maximum compare value stored in the
timer reload high and low byte registers. The timer input is the system clock. On reaching
the compare value, the timer generates an interrupt and counting continues (the timer
value is not reset to
timer output pin changes state (from low to high or from high to low) upon compare.
If the timer reaches
Follow the steps below for configuring a timer for COMPARE mode and for initiating the
count:
1. Write to the timer control register 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 compare value.
4. Enable the timer interrupt and set the timer interrupt priority by writing to the relevant
5. If using the timer output function, configure the associated GPIO port pin for the timer
6. Write to the timer control register to enable the timer and initiate counting.
In COMPARE mode, the system clock always provides the timer input. The compare time
can be calculated by the following equation:
