Abstract
An intermediate voltage is maintained between a first voltage and a second voltage by conditionally or selectively performing data bus inversion (DBI) and/or data swap operations on a first and second transmit channel. The operations are performed to, in some instances, create a current imbalance between the first and second channel where the intermediate voltage drifts toward a target range or target value between the first voltage and second voltage in response to the created imbalance.
