Abstract

Embodiments of a device and method are disclosed. In an embodiment, a method for communicating data frames on a bus that operates according to a multi-master bus protocol is disclosed. The method involves beginning transmission of a data frame from a node on the bus when the node gains control of the bus, wherein the multi-master bus protocol specifies a frame format that includes a start portion, a payload portion, and an end portion, during transmission of the payload portion of the data frame, inserting an in-payload arbitration field into the transmission, continuing transmission of the data frame if the node maintains control of the bus after insertion of the in-payload arbitration field, and halting transmission of the data frame before transmission of the data frame is complete if the node losses control of the bus after insertion of the in-payload arbitration field.
