Notes

1.Interrupt from the PCI/ISA Bridge.

2.Interrupt from the Falcon chip set for a single and/or double bit memory error.

3.The mapping of interrupt sources from the VMEbus and Universe internal interrupt sources is programmable via the Local Interrupt Map 0 Register and the Local Interrupt Map 1 Register in the Universe ASIC.

4.These interrupts also appear at the PIB for backward compatibility with older MVME1600 and PM603/4 modules.

8259 Interrupts

There are 15 interrupt requests supported by the PIB. These 15 interrupts are ISA-type interrupts that are functionally equivalent to two 82C59 interrupt controllers. Except for IRQ0, IRQ1, IRQ2, IRQ8_, and IRQ13, each of the interrupt lines can be configured for either edge-sensitive mode or level-sensitive mode by programming the appropriate ELCR registers in the PIB.

There is also support for four PCI interrupts, PIRQ3_-PIRQ0_. The PIB has four PIRQ Route Control registers to allow each of the PCI interrupt lines to be routed to any of eleven ISA interrupt lines (IRQ0, IRQ1, IRQ2, IRQ8_, and IRQ13 are reserved for ISA system interrupts). Since PCI interrupts are defined as level-sensitive, software must program the selected IRQ(s) for level-sensitive mode. Note that more than one PCI
