Interrupt Handling

5-3

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 

 for details on the RavenMPIC. The following table 

shows the interrupt assignments for the RavenMPIC on MVME2300 
series boards:
