Signal levels on pins D and D are determined by other USB devices and external pull-up or
pull-down resistors.
In the suspend mode (pin SUSPND = HIGH), the differential receiver is inactive and the output RCV is
always LOW. Out-of-suspend (K) signalling is detected via the single-ended receivers VP and VM.
VP = VM = H indicates the sharing mode (V
RCV* denotes the signal level on output RCV just before the SE0 state occurs. This level is stable
during the SE0 period.
