Potentiometer
The DEMO9S08LG32 target board provides a 5K ohm potentiometer (POT) to simulate analog
input. The POT is decoupled to minimize noise during adjustment. The POT is selectively
assignable to ADC6 or ADC7 by the ADC option header.
The ADC option header also controls POT configuration. The POT may be configured as a
variable pull-down resistance or may be connected to VDDA as a variable voltage input.
Figure 11 below shows the ADC option header selections.

User LED’s
The DEMO9S08LG32 target board provides 8, green, LEDs for output indication. Each LED is
configured for active-low operation. A series, current-limit resistor prevents excessive diode
current. Figure 12 below shows the USER1 enable position and associated signal for each
LED.
