Lower level drivers are responsible for - Reporting VBUS status and activating VBUS - Setting CC lines and providing CC line status - Setting line polarity - Activating and deactivating VCONN - Setting the current limit - Activating and deactivating PD message transfers - Sending and receiving PD messages The driver provides both a functional API as well as callbacks for lower level drivers.
