I would like to know how to do the following: I have a board which can operate in either interrupt driven mode, or polled mode, via an installed jumper. I would like to detect which mode during startup. I can force an interrupt to be generated by the unit during startup, however, what happens to interrupts for units before they have been attached? Is there some way to detect that an interrupt was generated by my actions?
