Abstract

Various embodiments include methods for implementing command transactions on a two-wire bus system of a computing device, and devices for implementing the methods. Embodiments may include receiving, by a two-wire interface of a host device, an abort signal via a two-wire bus, and transmitting, by the two-wire interface of the host device, an end signal via the two-wire bus in response to receiving the abort signal. Embodiments may further include transmitting, by a two-wire interface of a bus owner device, commands via the two-wire bus prior to receiving the end signal, receiving, by the two-wire interface of the bus owner device, the end signal via the two-wire bus; and terminating, by the two-wire interface of the bus owner device, transmitting commands in response to receiving the end signal. Some embodiments may include transmitting the commands following an instance of bus arbitration and prior to a subsequent instance of bus arbitration.
