 *       Description : Create
 *
 *  This example project shows how to use the IAR Embedded Workbench for ARM
 * to develop code for the IAR LPC-1788 board. It shows basic use of the I/O,
 * the timer and the interrupt controllers.
 *  It starts by blinking USB Link LED.
 *
 * Jumpers:
 *  EXT/JLINK  - depending of power source
 *  ISP_E      - unfilled
 *  RST_E      - unfilled
 *  BDS_E      - unfilled
 *  C/SC       - SC
 *
 * Note:
 *  After power-up the controller get clock from internal RC oscillator that
 * is unstable and may fail with J-Link auto detect, therefore adaptive clocking
 * should always be used. The adaptive clock can be select from menu:
 *  Project->Options..., section Debugger->J-Link/J-Trace  JTAG Speed - Adaptive.
