4.2.2 Mechanical Switch
The PIC18F57Q84 Curiosity Nano board has one mechanical switch, which is a generic user-configurable switch. Pressing the switch will drive the I/O line to ground (GND).
Tip: There is no externally
connected pull-up resistor on the switch. Make sure that an internal pull-up resistor is
enabled on pin RA3 to use the
switch.
