/* LEDs
 *
 * The launchpad has several LEDs:
 *
 *   - LEd D1 (white) that connects to the USB +5V supply,
 *   - LED D10 (red) that connects to the TMS570's NERROR pin,
 *   - D5 (blue), D6 (blue), and D8 (blue) connect to the XDS100 FT2322,
 *   - D7 (blue) connects to the XSD100 CPLD, and
 *   - Two white, user LEDs labeled D12 that connects to the NHET08
 *     pin and D11 that connects to GIOA2.
 *
 * NHET08 is one of 32 N2HET pins than can be available to the user if not
 * used by N2HET.  This implementation, however, uses only the single LED
 * driven by GIOA2.  That LED is tied to ground and illuminated with a high
 * level output value.

/* Buttons
 *
 * The launchpad has three mechanical buttons. Two of these are reset
 * buttons:  One button is labeled PORRST performs a power-on reset and one
 * labeled RST performs an MCU reset.  Only one button is available for
 * general software usage.  That button is labeled GIOA7 and is, obviously,
 * sensed on GIOA7.
 *
 * GIOA7 is tied to ground, but will be pulled high if the GIOA7 button is
 * depressed.
