Buttons schematic
Example of button connection to PORTD low and PORTD high is shown in Fig.18. Jumper
J11 determines whether a button press will bring logical zero or logical one to the appropri-
ate pin.
When the button is not pressed, the pin state is determined by the pull-up or pull-down port
jumpers.
In the example shown in Fig.18, J11 is connected to +5V and a button press will bring log-
ical one to the appropriate pins.
