USB mode
VP_VM
DAT_SE0
Some of the modes and signals are provided to achieve backward compatibility with IP cores.
TxD+ and TxD are single-ended inputs to drive the DP and DM outputs, respectively, in single-ended mode.
RxD+ and RxD are the outputs of the single-ended receivers connected to DP and DM, respectively.
TxD is the input to drive DP and DM in DAT_SE0 mode.
FSE0 is to force an SE0 on the DP and DM lines in DAT_SE0 mode.
RxD is the output of the differential receiver.
RSE0 is an output indicating that an SE0 has been received on the DP and DM lines.
