USER OPTIONS
The DEMO9RS08KB12 includes various input and output devices to aid application
development and debug. User I/O includes 2 momentary pushbutton switches, 2 green LEDs,
1 potentiometer, 1 Light Sensor. Each device may be enabled or disabled individually with the
USER_EN option header. Each user enable is clearly marked as to functionality.
Pushbutton Switches
Two push button switches provide momentary, active-low input, for user applications. External pull-
ups internal bias the switches for proper operation. Pushbutton switches SW1 and SW2 are
enabled to the MCU I/O ports by the USER_EN option bank. Figure 8 below shows the jumper
setting for the pushbutton switches.
LED Indicators
Two LEDs provide visual output for user applications. Both LEDs are configured for active-low
operation. Figure 8 below shows the jumper setting for the LED’s.
Potentiometer
A 5k ohm, thumb-wheel type, potentiometer at RV1 provides variable resistance input for user
applications. The output is the result of a voltage divider that changes as the thumb-wheel is
turned. The potentiometer is connected between VDD and GND with the center tap providing the
divider output. Figure 8 below shows the jumper setting for the POT.
Light Sensor
A surface-mount phototransistor, at RZ1, provides light sensitive, variable input for user
applications. Current flow within the phototransistor is inversely proportional to light intensity
incident on the surface of the device. A rail-to-rail OP amp at U5 boosts the photocell output to
useable levels. Figure 8 below shows the jumper setting for the Light Sensor.
