Abstract
A device (102) includes a transmission circuit that is configured and arranged to transmit data in accordance with a signal bus protocol that uses passive bias (114) to set a signal bus to a recessive value in the absence of an actively-driven signal value. The transmission circuit includes a first driver circuit (108,110) that is configured and arranged to actively drive the signal bus to a dominant value that is different from the recessive value. The transmission circuit also includes a second driver circuit (106,112) that is configured and arranged to actively drive the signal bus to the recessive value. A control circuit (104) is configured and arranged to disable the second driver circuit (106,112) in response to the device operating in a first data transmission mode, and to enable the second driver circuit (106,112) in response to the device entering a second transmission mode.
