In the USB suspend mode, the ISP1301 can drive the DP and DM lines, if the OE_N/INT_N input
(when the OE_INT_EN bit is not set) is LOW. In such a case, these outputs are driven as in the USB
functional modes, but with the full-speed characteristics, irrespective of the value of the SPEED input
pin or the SPEED_REG bit.

Some of the modes and signals are provided to achieve backward compatibility with IP cores.
TxD+ and TxD
are single-ended inputs for driving the DP and DM outputs, respectively, in the single-ended mode.
RxD+ and RxD
are the outputs of the single-ended receivers connected to DP and DM, respectively.
TxD is the input for driving DP and DM in the DAT_SE0 mode.
FSE0 is for forcing an SE0 on the DP and DM lines in the 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.
