Abstract
An input/output interface is used to transmit data between a transmitting circuit and a receiving circuit. Selectively during both system startup and system operation, a known bit pattern transmitted by the transmitting circuit is compared to a received bit pattern. The received bit pattern may be seen at the receiving circuit or a voltage regulator that is used to control the power supply level of the input/output interface. Dependent on the comparison of the known bit pattern and the received bit pattern, a bit error rate across the input/output interface is determined, in response to which the voltage regulator adjusts the power supply level of the input/output interface.
