4Hawk Programming Details

Introduction

This chapter contains details of several programming functions associated
with the Hawk ASIC chip.

PCI Arbitration

PCI arbitration must be provided by the host board.
Hawk MPIC External Interrupts
The MVME5100 Hawk MPIC is fully compliant with the industry
standard Multi-Processor Interrupt Controller Specification. Following a
power-up reset, the MPIC is configured to operate in the parallel interrupt
delivery mode on the MVME5100 series:
MPIC Edge/
IRQ Level
IRQ0 Level
IRQ1 Level
IRQ2 Level
IRQ3 Level
IRQ4 Level
IRQ5 Level
IRQ6 Level
IRQ7 Level
IRQ8 Level
