When processing an interrupt exception, the processor first makes an internal
copy of the status register, sets the privilege level to supervisor, suppresses
tracing, and sets the processor interrupt mask level to the level of the interrupt
that cannot supply an interrupt vector, the autovector signal (AVEC) can be
being serviced. The processor attempts to obtain a vector number from the
interrupting device using an interrupt acknowledge bus cycle with the inter-
rupt level number output on pins A1-A3 of the address bus. For a device
asserted, and the MC68030 uses an internally generated autovector, which
is one of vector numbers 25-31, that corresponds to the interrupt level num-
ber. If external logic indicates a bus error during the interrupt acknowledge
cycle, the interrupt is considered spurious, and the processor generates the
spurious interrupt vector number, 24. Refer to 7.4.1 Interrupt Acknowledge
Bus Cycles for complete interrupt bus cycle information.
