Installing a Callback Function

While applications can install hardware interrupt service routines (ISRs)
directly to process interrupts from timers (see
timer service provides a simple, easy-to-use callback mechanism that
provides equivalent functionality.
The following code fragment illustrates how to install a callback function.
Different callback functions can be used for each timer, or a single call-
back function can be used for any number of timers. The fragment shows
installation of a single callback function for two general-purpose timers,
the core timer, and a watchdog timer. The switch statement within the
callback function identifies which timer generated the callback.
