2.1.3.3 Verify Hardware Connection

After the GUI establishes connection with the EVM through USB, you can verify the communication with the MCx8316 device by clicking on the "Read All Registers" button on the top right of this GUI. After a few seconds, the GUI should indicate with a pop-up notification that all registers have been read back successfully.
