The timer is a down counter with a 24-bit reload/tick value that is clocked by the FastClk/SlowClk. The timer has the capability to generate an interrupt when the set number of ticks expires and the counter is reloaded. This interrupt is available as part of the Nested Vectored Interrupt Controller (NVIC ...
