PCI Bus IDSEL Mapping and IRQ Routing
The IRQ´s of the different PCI devices on the EBC2 must be distributed to the four PCI inter-
rupts (INTA#, INTB#, INTC#, INTD#) of the E²Brain™ module. In the same manner, different
PCI ADxx lines from the E²Brain™ module must be connected to the IDSEL input of the PCI
devices on the EBC2.
The following table provides the realized routing on the EBC2 with the corresponding PCI de-
vice.
