Abstract:
1. A method of clock-independent communication of data bits between devices, comprising the steps of: providing a pair of data signal lines interconnecting said devices, for transmission of said data bits; indicating the transmission of a data bit by a state change on one of said two data signal lines, independent of any clock signal; indicating that a value of said transmitted data bit is one by state transitions between values occurring on a first one of said pair of data signal lines interconnecting said devices; and indicating that a value of said transmitted data bit is zero by said state transitions between values occurring on a second one of said pair of data signal lines interconnecting said devices, wherein the state transitions between values only occur on one of said first and second data signal lines for said data bit communication at any one time, each such transition indicating the transmission of a data bit.
