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.

Crystals
The SAM4E Xplained Pro kit contains two crystals that can be used as clock sources for the SAM4E device.
Each crystal has a cut-strap next to it that can be used to measure the oscillator safety factor. This is done by
