 * \page sam4c_ek_board_desc SAM4CMP-DB - Board Description
 *
 * \section Purpose
 *
 * This file is dedicated to describe the SAM4CMP-DB board.
 *
 * \section Contents
 *
 *  - For SAM4CMP-DB information, see \subpage sam4c_ek_board_info.
 *  - For operating frequency information, see \subpage sam4c_ek_opfreq.
 *  - For using portable PIO definitions, see \subpage sam4c_ek_piodef.
 *  - For External components, see \subpage sam4c_ek_extcomp.
 *  - For Individual chip definition, see \subpage sam4c_ek_chipdef.
 *
 * To get more software details and the full list of parameters related to the
 * SAM4CMP-DB board configuration, please have a look at the source file:
 * \ref board.h\n
 *
 * \section Usage
 *
 *  - The code for booting the board is provided by board_cstartup_xxx.c and
 *    board_lowlevel.c.
 *  - For using board PIOs, board characteristics (clock, etc.) and external
 *    components, see board.h.
 *  - For manipulating memories, see board_memories.h.
 *
 * This file can be used as a template and modified to fit a custom board, with
 * specific PIOs usage or memory connections.
