/// \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_#.
