Referring to figure 22,
jumper J3 is set to pull-up
position so that pull-up resis-
tor pulls the microcontroller
pin PC2 pin to +5V. By
pressing the button, the PC2
pin will be connected to
ground via J12.
Accordingly, only when the
button is pressed the micro-
controller senses a logic zero
(0). Otherwise, the pin state
will always be logic one (1).
Referring to Figure 23,
jumper J3 is set to pull-down
position so that pull-down
resistor pulls the microcon-
troller pin PC2 to 0V. By
pressing the button, the PC2
pin will be connected to +5V
via J12.
Accordingly, only when the
button is pressed the micro-
controller senses a logic one
(1). Otherwise, the pin state
will always be logic zero (0).
