37.5.7 Calibration

The output drivers for the DP/DM USB line interface can be fine tuned with calibration values from production tests. The calibration values must be loaded from the CAL OTP memory region into the USB Pad Calibration register (PADCAL) by software, after enabling the USB, to achieve the specified accuracy. Refer to the CAL OTP Configuration section for additional information.

For additional information on Pad Calibration, refer to the Pad Calibration (PADCAL) register.
