 * \section intro Introduction
 * This example shows how to initialize the clock system and output the
 * CPU clock on a dedicated pin.
 *
 * \section files Main files:
 * - clock_example2_uc3.c: clock system example application
 * - conf_board.h: board initialization configuration
 * - conf_clock.h: system clock configuration
 * - conf_example2.h: chip- or board-specific example configuration
 *
 * \section deviceinfo Device Info
 * All AVR UC3 devices can be used.
 *
 * \section exampledescription Description of the example
 * This example makes use of the output GPIO function for a generic clock to
 * output the CPU clock on a pin.
 *
 * The generic clock and its corresponding GPIO pin and function are defined in
 * conf_example2.h.
 * The main system clock source and prescalers, along with any PLL
 * and/or DFLL configuration, if supported, are defined in conf_clock.h.
 *
 * \section compinfo Compilation Info
 * This software was written for the GNU GCC and IAR for AVR.
 * Other compilers may or may not work.
