Value Description
This bit indicates if Vbus is detected or not. The bit raises
immediately when Vbus becomes high. It drops to zero if Vbus is
low for at least 3 ms. If this bit is high and the DCon bit is set, the
hardware will enable the pull-up resistor to signal a connect.

the corrupted frame number as received by the device.
