Abstract
A driver circuit for a serial communication bus employs multiple switch circuits to generate different voltage levels on a set of signal lines included in the serial communication bus. The different voltage levels correspond to different values for a set of bits to be transmitted via the serial communication bus. The driver circuit also employs a shunt circuit that couples at least two of the signals together in response to the set of bits matching a particular data pattern.
