Notes:

1

The SERCOM4 module is shared between EXT1, 2 and 3 UART's, but uses different pins.

The SAM D20 Xplained Pro kit contains one crystals that can be used as clock source for the SAM D20 device.

The crystal has a cut-strap next to it that can be used to measure the oscillator safety factor. This is done by

cutting the strap and adding a resistor across the strap. More information about oscillator allowance and safety
