On-Chip Termination (OCT) Specifications
If you enable OCT calibration, calibration is automatically performed at power up for
I/O pins connected to the calibration block. Calibration accuracy for the calibrated
on-chip series termination (RS OCT) and on-chip parallel termination (RT OCT) are
applicable at the moment of calibration. When process, voltage, and temperature
(PVT) conditions change after calibration, the tolerance may change.
