Jumpers to disable all the user I/O functions from additional circuitry
powered DEMO via on-board voltage regulator (3.3V)
powered DEMO via on-board USB BDM (3.3V)
powered DEMO via on-board battery (3.0V)
supply 3.3V power to the MCU_PORT header if the board is
powered though the on-board regulator or USB
Use circuit components recommended by crystal manufacturer
and MCU data sheet.
