39.5.10 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 NVM Software Calibration Area into the USB Pad Calibration register (PADCAL) by software, before enabling the USB, to achieve the specified accuracy. Refer to NVM Software Calibration Area Mapping for further details.

For details on Pad Calibration, refer to Pad Calibration (PADCAL) register.
