WebNon-shared interrupts can be either level- or edge-triggered. Shared interrupts can only be level interrupts due to the chance of missed interrupts when edge interrupts are used. For example, let’s say DevA and DevB share an interrupt. DevB signals an interrupt, so INT line goes high. The ISR handler calls code for DevA but does nothing.
