SAM4E Xplained Pro

4.2.6 USB

The SAM4E Xplained Pro has a Micro-USB receptable for use with the SAM4E USB device module labeled "target usb" on the board. To be able to detect when a USB cable is connected, a GPIO (PE2) is used to detect the VBUS voltage on the connector.

Table 4-11 lists all I/O-lines connected to the USB connector.
