+/// \unit
+/// !Purpose
+/// 
+/// Definition of AT91SAM7S-EK characteristics, AT91SAM7S-dependant PIOs and
+/// external components interfacing.
+/// 
+/// !Contents
+/// This file provide a large number of definitions, which are of three
+/// different types.
+///
+/// PIO definitions are prefixed with #PIN_# or #PINS_#. They are to be used
+/// with the pio peripheral to configure the pins required by the application.
+///
+/// First, additional information about the platform is provided by several
+/// constants:
+///    - BOARD_NAME is a string containing the board name
+///    - The chip family and board (at91sam7s and at91sam7sek) are also
+///      provided.
+///    - BOARD_MAINOSC and BOARD_MCK contains the standard frequency for the
+///      main oscillator and the master clock.
+///
+/// Contants prefixed with #BOARD_USB_# give information about the USB device
+/// peripheral that is provided in the chip.
+///
+/// Defines prefixed with #PIN_# contain only one pin (and thus can be safely
+/// used to initialize a single Pin instance), whereas defines starting with
+/// #PINS_# contains either a single Pin instance with multiple pins inside it,
+/// or a list of several Pin instances; they must be used as Pin[] array
+/// initializer values, otherwise they are not safe.
+///
+/// Finally, some information about the flash controller is given by definitions
+/// prefixed with #BOARD_FLASH_#.
