Potentiometer
A 5k ohm, single-turn, thumb-wheel type, potentiometer at RV1 provides continuous, variable
resistance input for user applications. The potentiometer is connected between VDD and GND
with the center tap providing the divider output. The center tap is connected to the MCU at :

User Pushbutton Switches
Four user push-button switches are provided for user application input as needed and are con-
figured for active-low signaling. SW1 – SW4 are applied to keyboard interrupt inputs on the
target MCU. Use of target device internal pull-ups is required for proper operation. No external
bias is applied to any push-button switch input. Use of target device internal pull-ups is re-
quired for proper operation.

User LED’s
Eight user LED's are provided for output indication and are configured for active-low signaling.
