1. A method of operating a system that comprises a commander device and a set of responder devices coupled via a bus, the method comprising:
encoding messages addressed to responder devices in the set of responder devices in a CAN FD format using a serial peripheral interface (SPI) protocol, the messages comprising identifiers identifying respective ones of the responder devices to which the messages are addressed, wherein each message comprises a CRC field and a CRC delimiter following the CRC field;
transmitting the messages from the commander device over the bus;
receiving, by the responder devices, the messages transmitted from the commander device; and
verifying, by the responder devices, a correctness of the CRC field and a presence of the CRC delimiter.
