 * 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.
