Configuration

There are two configuration parameters in the CAN device. Firstly the config.interrupt property can be set to influence the interrupt that is raised with the IRQ controller. Setting that property also updates the AHB PnP info.

The second configuration property is config.infiniteSpeed. If that property is set, messages will be sent immediately instead of being scheduled.

The device should be connected to an interrupt controller and a CAN bus, to work properly.
