ABSTRACT:
A data processing system and a method for performing dynamic bus signal termination uses a dynamic bus termination circuitry (14 or 16) with a device (10 or 12). The circuitry is enabled when data is incoming to the device and is disabled when data is outgoing from the device to selectively reduce unwanted signal reflection at the signal end of a bi-directional bus (17). The disabling allows the circuitry to be removed or tristated from any connection with the bus (17) when not needed (i.e., data outgoing) to reduce loading. The disabling of the termination circuitry also aids in reducing the power consumption of the part when either the bus is sitting idle or the part is in a low power mode of operation.
