Abstract: Systems, methods, and apparatus are described that enable communication of signals over a serial data bus. A method performed at a transmitter/sender device coupled to the serial data bus includes determining at a transmitter on the serial data bus a condition whereby a receiver in communication with the transmitter on the serial data bus is initiating a termination of data transfer between the transmitter and the receiver. The method further includes calculating an error check word in the transmitter simultaneous with data transfer from the transmitter to the receiver, and temporarily taking control of the serial bus with the transmitter after initiation of the termination of data transfer and transmitting the calculated error check word to the receiver.
