+/// \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.
