A method and system for communicating at least two data transfers on a common bus. Data is communicated between a simple device and a system processor or system connector via the common bus at a low data rate, and data is communicated between a more complex device and the system processor or system connector via the common bus at a high data rate. Low data rate communications are conducted by selectively varying the voltage level on the common bus at least between a low voltage range and a high voltage range, wherein the low voltage range represents a first data value and the high voltage range represents a second data value. High data rate communications can be conducted, simultaneous with the low data rate communications, by selectively varying the voltage level on the common bus at least between two voltage sub-levels within the low voltage range and between two voltage sub-levels within the high voltage range.
