2.2 Task Manipulation
(1) Starting task
(2) Terminating task
RX78K/IV allows the following manipulation of tasks:
All the tasks created when the system is started are placed in the DORMANT state.
A task in the DORMANT state cannot be dispatched until it is started. Therefore, it must be placed in the READY
state by issuing system call “sta_tsk”.
A task can be terminated by system call “ext_tsk” (normal termination) or “ter_tsk” (forced termination).
* Interrupts are enabled when a task has been started for the first time. Disable interrupts for each task.
