Remarks

For information about Request Data Objects, see the Power Delivery specification. There are different types of Request Data Objects and the type depends on the Power Data Object that is specified in the ObjectPosition member of UCM_PD_REQUEST_DATA_OBJECT. The source buffer is little-endian format. The client driver can call the memcpy function to get the Request Data Objects from the hardware into an array of UCM_PD_REQUEST_DATA_OBJECT structures.
