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 through SW3 are applied to keyboard interrupt inputs on
the target MCU. SW4 is applied to a GPIO port pin. Use of target device internal pull-ups is
required for proper operation. No external bias is applied to any push-button switch input.

User LED’s
Eight user LED's are provided for output indication and are configured for active-low signaling.
The table below details the LED connections to the target MCU

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 on
two separate inputs:
NOTE: To use LED8, remove the RXCAN option jumper at the CAN_EN option header.
