Appendix D User Interrupts
If an interrupt occurs while a higher priority interrupt is being serviced
(executed), and the pending bit has been set for the lower priority interrupt,
the currently executing interrupt routine continues to completion. Then the
lower priority interrupt runs before returning to normal processing.
User Interrupt Configuration
User interrupts can be configured and set as AutoStart from the Interrupts
window.
