+/// \dir "USB device CCID project with AT91SAM Microcontrollers"
+///
+/// !!!Purpose
+///
+/// This example demonstrates the CCID (USB Chip/Smart Card Interface Devices) on AT91
+/// microcontrollers.
+///
+/// !!!Requirements
+///
+/// This example can be used on AT91SAM9260-EK, AT91SAM9263-EK, AT91SAM9G20-EK,
+/// AT91SAM9XE-EK.
+///
+/// !!!Description
+///
+/// This application implement a CCID driver.<BR>
+/// Different tests can be done with the Windows(c) software Smart Access(c).<BR>
+/// Smart Access: a powerful scripting tool to write sequences of commands.
+///
+/// !!!Usage
+///
+/// -# Install Smart Access(c) software.
+/// -# Build the program and download it inside the evaluation board. Please
+/// refer to the <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6224.pdf">SAM-BA User Guide</a>,
+/// the <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6310.pdf">GNU-Based Software Development</a>
+/// application note or to the <a href="ftp://ftp.iar.se/WWWfiles/arm/Guides/EWARM_UserGuide.ENU.pdf">IAR EWARM User Guide</a>,
+/// depending on your chosen solution.
+/// -# On the computer, open and configure a terminal application (e.g.
+/// HyperTerminal on Microsoft Windows) with these settings:
+/// - 115200 bauds
+/// - 8 data bits
+/// - No parity
+/// - 1 stop bit
+/// - Hardware flow control (RTS/CTS)
+/// -# Start the application. The following traces shall appear on the terminal:
+/// \code
+/// -- USB Device CCID Project xxx --
+/// -- AT91xxxxxx-xx
+/// -- Compiled: xxx xx xxxx xx:xx:xx --
+/// \endcode
+/// -# Connect the USB cable to the board. Traces should start to appear on the terminal.<BR>
+/// If this is the first time the device is connected to the PC,
+/// the operating system may take some time to install it.
+/// -# The device is enumerated as a Smart Card Device implementing CCID class.<BR>
+/// -# The host use the CCID device driver (usbccid.sys) as the functionnal driver.
+/// -# Launch Smart Access and connect it to the Card Reader Atmel.<BR>
+/// Use Smart Access for launch instruction command.<BR>
+/// Note that instruction command case one, two and three are implemanted.
+///
+/// !!!Contents
+///
+/// The definitions and functions provided are dispatched inside a number of
+/// files:
+/// - main.c main software
+//------------------------------------------------------------------------------
+
+
+
+/// \unit
+///
+/// !Purpose
+/// Implementation of the USB CCID.
+///
+/// !Contents
+/// The code can be roughly broken down as follows:
+/// - Configuration functions
+/// - Interrupt handlers
+/// - Utility functions
+/// - The main() function, which implements the program behavior
+/// - Use ICC insertion event() and CCID_SmartCardRequest() CCID functions
+///
+/// Please refer to the list of functions in the #Overview# tab of this unit
+/// for more detailed information.
