Mechanical Switch

ATtiny1607 Curiosity Nano has one mechanical switch. This is a generic user configurable switch. When the switch is pressed, it will drive the I/O line to ground (GND).

Tip: There is no externally connected pull-up resistor on the switch. To use the switch, make sure that an internal pull-up resistor is enabled on pin PC4.
