-/**
- * @file IxTimerCtrl.h
- * @brief
- * This is the header file for the Timer Control component.
- *
- * The timer callback control component provides a mechanism by which different
- * client components can start a timer and have a supplied callback function
- * invoked when the timer expires.
- * The callbacks are all dispatched from one thread inside this component.
- * Any component that needs to be called periodically should use this facility
- * rather than create its own task with a sleep loop.
