The logic state of all microcontroller input pins may be changed by means of push buttons. Jumper J10 is used to determine the
logic state to be applied to the desired microcontroller pin by pressing appropriate push button. Right next to the push buttons,
there is a RESET button which is used to provide the MCLR pin with the microcontroller reset signal over the programmer provided
on the MCU card.

In Figure 15-2, jumper J10 is in the VCC position. In this case, by pressing any push button, a logic one (5V) will be applied to the
appropriate microcontroller pin.
