4.4.8 Mechanical Buttons

AVR-IoT Wx contains two mechanical buttons. These are generic user-configurable buttons. When a button is pressed, it will drive the connected I/O line to ground (GND).

Info: There are no pull-up resistors connected to the generic user buttons. Remember to enable the internal pull-up in the ATmega4808 to use the buttons.
