  • Page 45: Considerations On Interrupt Service Routine (Isr)

    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.
