PURPOSE: A driver with impedance control is provided to control the output impedance of a driver circuit by inactivating or activating an individual sub circuit. CONSTITUTION: The driving strength for programming an interface circuit with a plurality of driver circuits is determined(510). A sub set of the plurality of the driver circuits is activated based on the driving strength(520). The impedance of one or more driver circuits is set in the sub set of the activated driver circuits based on an operation condition of the interface circuit(530). [Reference numerals] (510) Determining a programmable driving intensity; (520) Activating a sub set of driver circuits; (530) Setting impedance of driver circuits; (540) Is a condition changed?; (AA) Start; (BB) Yes; (CC) No; (DD) Finish
