Discussion
This routine is can be called whenever it is desirable to allow another task to run that is ready to run. One
particular situation in which it is useful is at the end of a long process during which UpdateRTC() has
been called one or more times. Normally, when an RTC interrupt occurs a task switch is performed
immediately if the current task’s time slice has expired or if a task is awaiting the expiration of an interval
and the interval period has elapsed. However, if interrupts are disabled this automatic task switch cannot
be performed. A call to UpdateRTC() will prepare the system for an eventual task switch which is then
triggered by a call to Yield().
Example
See the example at UpdateRTC.
