13. Push buttons
The logic level of all microcontroller input pins may be changed by using push buttons� Jumper J13 is used to determine
the logic level to be supplied on the appropriate microcontroller pin by pressing a push button� The function of the protec-
tive resistor is to limit the maximum current, thus preventing the development system and peripheral modules from being
damaged in case a short circuit occurs� If needed, advanced users may shorten this resistor by using jumper J12�
By pressing any push button when jumper J13 is in the VCC-BRD position, a logic one (3�3V or 5V) will be applied to the
appropriate microcontroller pin, as shown in Figure 13-2�
