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
