These service calls cancel the WAITING state (sleeping state) of the task specified by parameter
tskid.
As a result, the target task is moved from the sleeping state to the READY state, or from the WAITING-SUSPENDED state to the SUSPENDED state.
If the target task is in a state other than the sleeping state when this service call is issued, this service call does not move the state but increments the wake-up request counter (by added 1 to the wake-up request counter).
Note The wake-up request counter managed by the RI600V4 is configured in 8-bit widths. If the number of wake-up requests exceeds the maximum count value 255 as a result of issuing this service call, the counter manipulation processing is therefore not performed but "E_QOVR" is returned.
