Consider a CAN network that has a variable transmission rate, where the time in between messages can vary from tmin to tmax. Consider a particular listener on the network that will receive all messages (no filter). If the receive queue in this listener already has five unread messages, then additional CAN transmissions will stall on the network, because this receiver cannot acknowledge any more messages. In order to prevent stalling, this listener requires a real-time interface. The interface latency in this case is defined as the between the Receive CAN Flag (RXF) being set and the execution of the CAN interrupt 38. You may assume executing each CAN ISR will quickly read and remove all messages in its receive queue (clearing RXF). What is the upper bound on the interface latency?
