Function
These bits are not implemented.
This bit configures the way USB port 2
interfaces with external USB transceiver.
0: Bidirectional mode
USB2.SE0 is a bidirectional I/O, rather than
an output only.
Input of the USB2.SE0 bidirectional I/O is
connected to usb2_vm port of the USB OTG
module.
USB2.TXD is a bidirectional I/O, rather than
an output only.
Input of the USB2.TXD bidirectional I/O is
connected to USB2.VP port of the USB OTG
module.
1: Unidirectional mode
This bit configures the way USB port 1
interfaces with external USB transceiver.
0: Bidirectional mode
USB1.SE0 is a bidirectional I/O, rather than
an output only.
Input of the USB1.SE0 bidirectional I/O is
connected to USB1.VM port of the USB OTG
module.
USB1.TXD is a bidirectional I/O, rather than
an output only.
Input of the USB1.TXD bidirectional I/O is
connected to USB1.VP port of the USB OTG
module.
