USER I/O
User I/O includes 1 potentiometers, 1 Light Sensor, 2 push button switches, and 2 green LEDs
for user I/O. The User option header block enables or disables each User I/O function indi-
vidually.
Potentiometer
The DEMO9S08SH8 target board provides a 5K ohm potentiometer (POT) to simulate analog
input. The POT is decoupled to minimize noise during adjustment. Potentiometer RV1 con-
nects to analog input PTA0. The figure below shows the USER enable position and associ-
ated signal for the potentiometer.
Switches
The DEMO9S08SH8 provides 2 push button switches for user input. Each push button switch
provides an active low input with a pull-up resistor bias to prevent indeterminate input condi-
tions. Pressing a push-button switch causes a low logic input on the associated input. The fig-
ure below shows the USER enable position and associated signal for each user switch.
LED’s
The DEMO9S08SH8 target board provides 2 green LEDs for output indication. Each LED is
an active low output. Writing a low logic level to an LED output causes the associated LED to
turn on. A series, current-limit resistor prevents excessive diode current. The figure below
shows the USER enable position and associated signal for each user LED.

The following table shows the connections for each user I/O device.
