* When using Power and calibrateRCOSC is set to true, this should be set to 10.
* The timer used by the Clock module supports TickMode_DYNAMIC. This enables us
* to set the tick period to 10 us without generating the overhead of additional
* interrupts.
*
* Note: The calibrateRCOSC parameter is set within the Power configuration
* structure in the "Board.c" file.
