3.1Interrupts

The Intel® 80321 I/O Processor is built around an Intel XScale® core, which has four external interrupt lines designated XINT0# through XINT3#. In the 80321 processor, these interrupt lines are not directly connected to external interrupts, but pass through a layer of external interrupt routing logic. Figure 4 shows the interrupt connections on the processor.

The external devices are AND-gated into designated interrupt signals. Therefore, the specific device that generates the interrupt cannot be detected. However, the eight GPIO pins of the Intel® 31154 133 MHz PCI Bridge are used to read interrupts from the specific device, as shown in Table 8.
