CAUSE: The specified I/O uses a left-shifted on-chip termination (OCT) code. The shifter is used to drive I/O buffers with different impedance values than the external reference resistors that their termination calibration block drives. This information message may also appear when a bidirectional I/O that uses both the input and output termination has a different impedance value for the input and output termination.
ACTION: No action is required.
