1.6

PCI Global Interrupt Registers

The PCI Global Interrupt Control Registers are used to enable /disable and check

the status of interrupts generated on the PCI bus. These registers are located in

Page 0 of the

DAS-429PCI/Mx

Note:

To generate interrupts on the PCI bus, the interrupt condition registers in

Modules 0-3 must be programmed according to the interrupt conditions

desired.

1.6.1

PCI Interrupt Status Register

The PCI Interrupt Status register is used to determine the source of the board

generated PCI bus interrupt, Module 0-3.

1.6.2

PCI Interrupt Control Register

The PCI Interrupt Control register provides a global enable/disable of board

generated PCI interrupts.
