Considerations on Interrupt Service Routine (ISR)

Fully understand the restrictions of VxWorks, operating system, before creating a routine which is executed in an interrupt
service routine (ISR: InterruptServiceRoutine). To use another dedicated function by synchronizing it to an interrupt,
implement the notification processing in a user program and perform it in a task.
Setting an inappropriate value or executing a function other than a C Controller module dedicated function for
ISR from an interrupt service routine may cause the VxWorks runaway.
