/* There are four LEDs on the top, red side of the board.  Only one can be

 *
 *   LED L      - RB14 (SPI3_SCK)
 *
 * There are also four LEDs on the back, white side of the board:
 *
 *   LED A      - RA6
 *   LED B      - RA7
 *   LED C      - RE0
 *   LED D      - RE1

 * A high output value illuminates the LEDs.
