SERCOM4
Button
------
SAM L21 Xplained Pro contains one mechanical button on PA02 that can be
controlled by software. When a button is pressed it will drive the I/O
line to GND. Note: There is no pull-up resistor connected to the generic
user button. Remember to enable the internal pull-up in the SAM L21 to
use the button.
SERCOM4 is available on connectors EXT1, EXT2, and EXT3, but using
