Abstract
An interrupt handler may be run in multiple processor modes on a data processing system having a processor for executing instructions and a memory for storing information. The sharing of interrupt handler code across multiple processor modes minimizes the switching between processor modes during the handling of interrupts. The mode in which the interrupt handler executes is dictated by the current processor mode. The indicator of the current processor mode directs the interrupt handler to use information that is appropriate for the current processor mode.
