SAM D11 Xplained Pro

4.2.1 Crystal

The SAM D11 Xplained Pro kit contain one crystal footprint that can be used for mounting a clock source for the SAM D11 device. The I/O pins for the crystal are shared with the extension header, so two 0Ω resistors (R311 and R312) must be removed before mounting a crystal on the footprint.
