Table 5-2. Ravenmpic Interrupt Assignments; Ravenmpic - Motorola MVME2600 Series Reference Manual

RavenMPIC

The Raven ASIC has a built-in interrupt controller that meets the Multi-
Processor Interrupt Controller (MPIC) Specification. This MPIC supports
up to two processors and 16 external interrupt sources. There are also six
other interrupt sources inside the MPIC: Two cross-processor interrupts
and four timer interrupts. All ISA interrupts go through the 8259 pair in the
PIB. The output of the PIB then goes through the MPIC in the Raven.
Refer to Chapter 2 on the Raven for details on the RavenMPIC. The
following table shows the interrupt assignments for the RavenMPIC on the
MVME2600/2700 series:
