|
* supposed to return immediately because the event flags are already
|

* - [4.2.2] The pending event flags mask is cleared then the function
|
|
* chEvtWaitAnyTimeout() is invoked, after return the events mask is
|
|
* tested. The thread is signaled by another thread.
|
|
* - [4.2.3] The function chEvtWaitAnyTimeout() is invoked, no event
