Interrupt Handling
The Raven ASIC, which controls PHB (PCI Host Bridge) MPU/local bus
interface functions on the MVME2603/2604, performs interrupt handling
as well. Sources of interrupts may be any of the following:
interface functions on the MVME2603/2604, performs interrupt handling
as well. Sources of interrupts may be any of the following:
❏
The Raven ASIC itself (timer interrupts or transfer error interrupts)
❏
The processor (processor self-interrupts)
❏
The Falcon chip set (memory error interrupts)
❏
The PCI bus (interrupts from PCI devices)
❏
The ISA bus (interrupts from ISA devices)
