Interrupt Mode

The cifX device can be used in polling or interrupt mode.

If interrupt mode should be used, IRQ resource limitations must be considered.
As INtime® does not support sharing IRQ lines with Windows® devices, the interrupt line which
INtime® 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 INtime® due to IRQ resource limitations,
please consult the following tenASYS manual:

MSI Message Based Interrupts

Hilsche CIFX PCIexpress cards are currently supporting only LEGACY interrupts.

DMA Support

 DMA can be used in polling and interrupt mode.
