<p>Apparatus comprising a communication circuitry configured to drive a transition of an electrical parameter on an electrical interface to a apparatus, a determination circuitry configured to determine feedback information dependent upon a measured electrical parameter on the interface and a control circuitry configured to use the determined feedback information to control the power output of the communication circuitry to achieve a transition of the electrical parameter on the electrical interface within a threshold time period. The interface may be a bus such as USB or 12C and the determination circuitry may comprise a counter initiating the process. A lower interference, lower power consumption and greater tolerance of varying load capacitance is achieved.</p> |
