Priority and handler addresses for events
The interrupt system requires that an interrupt controller is present outside the core in order to
prioritize requests and generate a correct offset if more than one interrupt source exists for each
priority level. An interrupt controller generating different offsets depending on interrupt request
source is referred to as autovectoring. Note that the interrupt controller should generate
autovector addresses that do not conflict with addresses in use by other events or regular pro-
gram code.
