4.2.7 Example 9 – Timer

In this example, a COUNTER module is used to create timed events. The use of the GP Register is shown. Through setting/clearing the bits in the GP register, the timer is started, stopped or changes direction. The output of the timer event (1-clock cycle) is exported to a GPIO. Interrupts are generated from the timer event using the HLC module. A GPIO is also toggled inside the CLB ISR. The indirect CLB register access is used to update the timer’s event match value and the active counter register to modify the frequency of the timer.
