 * Demonstrates the CC1010 power modes: Idle and Stop mode                   *
 * - ENTER_IDLE_MODE and ENTER_SLEEP_MODE macros demonstrated                *
 *                                                                           *
 * The program can not be single-stepped in the debugger.                    *
 * The program can however be run stand-alone on the CC1010 EB.              *
 *                                                                           *
 * Pressing switch button 1 will start the program. Idle mode will be        *
 * entered and the green LED will light up when the timer 0 interrupt is     *
 * serviced. This brings the chip out of idle mode. Now, pressing switch     *
 * button 2 will light the yellow LED and enter sleep mode. When the reset   *
 * button is pressed the chip exits sleep mode and the LEDs go out.          *
