Precautions
• When an interrupt event has already been notified from a C Controller module (another CPU) at the time of the
CCPU_WaitEvent function execution, the user program is restored from the interrupt event wait state at the same time as
the function execution. In addition, when multiple interrupt events have been notified to the same interrupt event number at
the time of the CCPU_WaitEvent function execution, the user program processes them as a single interrupt event
notification.
• If the same CPU number and the same interrupt event number are set in more than one user program, it will be undefined
which one of the user programs receives the interrupt event.
