-        store it into NVS.
+        If this option is enabled, NVS will be initialized and calibration data will be loaded from there.
+        PHY calibration will be skipped on deep sleep wakeup. If calibration data is not found, full calibration
+        will be performed and stored in NVS. In all other cases, only partial calibration will be performed. 
 
         If unsure, choose 'y'.
