Table 2.50 CompactPCI Bus Interrupts

2.5 Interrupt Configuration

The CompactPCI specification defines a total of six interrupt signals on the backplane. INTA#

through INTD# are used to route interrupts from the CompactPCI boards to the PIC on the ‘proc-

essor board. The interrupt request level generated by the device depends on the backplane slot

number which the board is plugged into, and the interrupt signal which is driven by the particular

PCI device.

Note:

CompactPCI interrupts may be shared
