9.4.2.3
The SPURVEC register contains the interrupt vector number that is fed when a spurious interrupt event
occurs on the secondary interrupt controller. A spurious interrupt occurs when a pending interrupt causes
the ColdFire processor to feed an interrupt vector, but before the interrupt vector can be fed, the pending
interrupt disappears.

The 64 secondary interrupts used by the MCF5253 modules are provided in

This is the 8-bit interrupt vector for interrupt 0. Vector numbers for other interrupts are obtained by adding the
interrupt number to BASE. For example: Interrupt 23 vector is base + 23.
