Abstract: Systems, methods, and apparatus are described that enable communication of in-band reset signals over an I3C serial bus. A method performed at a slave device includes driving a data line of the I3C serial bus from a high state to a low state before a first clock pulse is received from a clock line of the I3C serial bus after a start condition has been provided on the I3C serial bus, where driving the data line from the high state to the low state produces an initial pulse on the data line, transmitting one or more additional pulses on the data line before the first clock pulse is transmitted on the clock line, and driving the data line low until a rising edge of the first clock pulse is detected on the clock line after each of the plurality of additional pulses has been successfully transmitted on the data line.
