This service call moves the invoking task from the RUNNING state to the WAITING state (sleeping state).
As a result, the invoking task is unlinked from the ready queue and excluded from the RI600V4 scheduling subject.
If a wake-up request has been queued to the target task (the wake-up request counter > 0) when this service call is issued, this service call does not move the state but decrements the wake-up request counter (by subtracting 1 from the wake-up request counter).
The sleeping state is cancelled in the following cases.
