The CANopen SDOs is a confirmed service, and overrun does not occur if the CAN controller
only communicates with the Gateway in the PRE-OPERATIONAL state. When a SDO has
been received by the controller no further communication takes place until the service has
been acknowledged (or a timeout occurs). However, other types of communication may fill
the Gateways internal buffer storage. In this event, the Gateway will issue an Overrun
Emergency message.
