Abstract
A method for transmitting data over a data bus with minimized digital control and data inter-symbol interference. The voltage level on the data bus is not permitted to reach the quiescent negated voltage level set by the bus terminator voltage. Additional time is provided for data detection circuitry to detect a first segment of data transferred over the data bus. A pause time is enabled after the data bus has been idle or paused for a prolonged period. After the first segment of data has been transferred, the method returns to normal operation by pausing for a normal period of time for data detection circuitry to detect subsequent segments of data transferred over the data bus. Additionally, during prolonged synchronous data transfers with unchanged data bits, the data bus is inverted and driven for further regulating the data bus voltage.
