Anybody out there who has a clue about the meaning of the VBUS bits of the Device Control Register (DEVCTL) ?
VBUS 0-3h These read-only bits encode the current VBus level as follows: 0 Below Session End. 1h Above Session End, below AValid. 2h Above AValid, below VBusValid. 3h Above VBusValid. What are the corresponding voltage levels on the Vbus line ? An additional hardware question: Should the VBUS pin of the DSP directly connect to the VBUS line of USB or is there a series resistor allowed or recommended ? thx a lot
If so, which maximum value ?
