Figure 21 illustrates the connection between push-buttons and the corresponding PORTC,

PORTA and PORTF pins. Jumper J12 determines whether a button press will bring logic zero
(0) or logic one (1) to the appropriate pin.
When button is released the pin state is determined by pull-up or pull-down resistors.
Referring to Figure 21, J12 is connected to +5V and any button press will therefore bring logic
one (1) to the appropriate pin.
