ext_tsk

Outline
Terminate invoking task.
C format
 void    ext_tsk (void);
Parameter(s)
None.
Explanation
This service call moves an invoking task from the RUNNING state to the DORMANT state.
As a result, the invoking task is unlinked from the ready queue and excluded from the RI850V4 scheduling subject.
If an activation request has been queued to the invoking task (the activation request counter is not set to 0x0) when this service call is issued, this service call moves the task from the RUNNING state to the DORMANT state, decrements the wakeup request counter (by subtracting 0x1 from the wakeup request counter), and then moves the task from the DORMANT state to the READY state.
Note 1 When moving a task from the RUNNING state to the DORMANT state, this service call initializes the following information to values that are set during task creation.
- Current priority
- Wakeup request count
- Suspension count
- interrupt state
If an invoking task has locked a mutex, the locked state is released at the same time (processing equivalent to unl_mtx).
Note 2 When the return instruction is issued in a task, the same processing as ext_tsk is performed.
Return value
None.
