+/// \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_#.

+///
+/// !Purpose
+///
+/// This module provides definitions and functions for using the Debug Unit
+/// (DBGU).
+///
+/// It also overloads the fputc(), fputs() & putchar() functions so the printf()
+/// method outputs its data on the DBGU. This behavior can be suppressed by
+/// defining NOFPUT during compilation.
+///
+/// !Usage
+///
+/// -# Enable the DBGU pins (see pio & board.h).
+/// -# Configure the DBGU using DBGU_Configure with the desired operating mode.
+/// -# Send characters using DBGU_PutChar() or the printf() method.
+/// -# Receive characters using DBGU_GetChar().
+///
+/// \note Unless specified, all the functions defined here operate synchronously;
+/// i.e. they all wait the data is sent/received before returning.

+/// !!!Purpose
+///
+/// This file provides a basic API for PIO configuration and usage of
+/// user-controlled pins. Please refer to the board.h file for a list of
+/// available pin definitions.
+///
+/// !!!Usage
+///
+/// -# Define a constant pin description array such as the following one, using
+/// the existing definitions provided by the board.h file if possible:
+/// \code
+/// const Pin pPins[] = {PIN_USART0_TXD, PIN_USART0_RXD};
+/// \endcode
+/// Alternatively, it is possible to add new pins by provided the full Pin
+/// structure:
+/// \code
+/// // Pin instance to configure PA10 & PA11 as inputs with the internal
+/// // pull-up enabled.
+/// const Pin pPins = {
+/// (1 << 10) | (1 << 11),
+/// AT91C_BASE_PIOA,
+/// AT91C_ID_PIOA,
+/// PIO_INPUT,
+/// PIO_PULLUP
+/// };
+/// \endcode
+/// -# Configure a pin array by calling PIO_Configure() with a pointer to the
+/// array and its size (which is computed using the PIO_LISTSIZE macro).
+/// -# Change and get the value of a user-controlled pin using the PIO_Set,
+/// PIO_Clear and PIO_Get methods.
+/// -# Get the level being currently output by a user-controlled pin configured
+/// as an output using PIO_GetOutputDataStatus().

+/// \unit
+///
+/// !!!Purpose
+///
+/// Configuration and handling of interrupts on PIO status changes. The API
+/// provided here have several advantages over the traditional PIO interrupt
+/// configuration approach:
+/// - It is highly portable
+/// - It automatically demultiplexes interrupts when multiples pins have been
+/// configured on a single PIO controller
+/// - It allows a group of pins to share the same interrupt
+///
+/// However, it also has several minor drawbacks that may prevent from using it
+/// in particular applications:
+/// - It enables the clocks of all PIO controllers
+/// - PIO controllers all share the same interrupt handler, which does the
+/// demultiplexing and can be slower than direct configuration
+/// - It reserves space for a fixed number of interrupts, which can be
+/// increased by modifying the appropriate constant in pio_it.c.
+///
+/// !!!Usage
+///
+/// -# Initialize the PIO interrupt mechanism using PIO_InitializeInterrupts()
+/// with the desired priority (0 ... 7).
+/// -# Configure a status change interrupt on one or more pin(s) with
+/// PIO_ConfigureIt().
+/// -# Enable & disable interrupts on pins using PIO_EnableIt() and
+/// PIO_DisableIt().

+/// !Purpose
+///
+/// Interface for configuration the Periodic Interval Timer (PIT) peripheral.
+///
+/// !Usage
+///
+/// -# Initialize the PIT with the desired period using PIT_Init().
+/// Alternatively, the Periodic Interval Value (PIV) can be configured
+/// manually using PIT_SetPIV().
+/// -# Start the PIT counting using PIT_Enable().
+/// -# Enable & disable the PIT interrupt using PIT_EnableIT() and
+/// PIT_DisableIT().
+/// -# Retrieve the current status of the PIT using PIT_GetStatus().
+/// -# To get the current value of the internal counter and the number of ticks
+/// that have occurred, use either PIT_GetPIVR() or PIT_GetPIIR() depending
+/// on whether you want the values to be cleared or not.

+/// !Purpose
+///
+/// This module provides several definitions and methods for using an USART
+/// peripheral.
+///
+/// !Usage
+/// -# Enable the USART peripheral clock in the PMC.
+/// -# Enable the required USART PIOs (see pio.h).
+/// -# Configure the UART by calling USART_Configure.
+/// -# Enable the transmitter and/or the receiver of the USART using
+/// USART_SetTransmitterEnabled and USART_SetReceiverEnabled.
+/// -# Send data through the USART using the USART_Write and
+/// USART_WriteBuffer methods.
+/// -# Receive data from the USART using the USART_Read and
+/// USART_ReadBuffer functions; the availability of data can be polled
+/// with USART_IsDataAvailable.
+/// -# Disable the transmitter and/or the receiver of the USART with
+/// USART_SetTransmitterEnabled and USART_SetReceiverEnabled.

+///
+/// !Purpose
+///
+/// Standard output methods for reporting debug information, warnings and
+/// errors, which can be easily be turned on/off.
+///
+/// !Usage
+/// -# Initialize the DBGU using TRACE_CONFIGURE() if you intend to eventually
+/// disable ALL traces; otherwise use DBGU_Configure().
+/// -# Uses the TRACE_DEBUG(), TRACE_INFO(), TRACE_WARNING(), TRACE_ERROR()
+/// TRACE_FATAL() macros to output traces throughout the program.
+/// -# Each type of trace has a level : Debug 5, Info 4, Warning 3, Error 2
+/// and Fatal 1. Disable a group of traces by changing the value of
+/// TRACE_LEVEL during compilation; traces with a level bigger than TRACE_LEVEL
+/// are not generated. To generate no trace, use the reserved value 0.
+/// -# Trace disabling can be static or dynamic. If dynamic disabling is selected
+/// the trace level can be modified in runtime. If static disabling is selected
+/// the disabled traces are not compiled.
+///
+/// !Trace level description
+/// -# TRACE_DEBUG (5): Traces whose only purpose is for debugging the program,
+/// and which do not produce meaningful information otherwise.
+/// -# TRACE_INFO (4): Informational trace about the program execution. Should
+/// enable the user to see the execution flow.
+/// -# TRACE_WARNING (3): Indicates that a minor error has happened. In most case
+/// it can be discarded safely; it may even be expected.
+/// -# TRACE_ERROR (2): Indicates an error which may not stop the program execution,
+/// but which indicates there is a problem with the code.
+/// -# TRACE_FATAL (1): Indicates a major error which prevents the program from going
+/// any further.
