The cifX device can be used in polling or interrupt mode.
If interrupt mode should be used, IRQ resource limitations must be considered.
As RTX® does not support sharing IRQ lines with Windows® devices, the interrupt line which
RTX® uses must be available for exclusive use.
Finding an exclusive IRQ often requires physically moving hardware around in the system or
disabling other Windows® devices.
If you have difficulty configuring your hardware for use with RTX® due to IRQ resource limitations,
please consult the following IntervalZero manual:.
