/**

 *
 *  \par Purpose
 *
 *  Methods and definitions for Global time tick and wait functions.
 *
 *  Defines a common and simplest use of Time Tick, to increase tickCount
 *  every 1ms, the application can get this value through GetTickCount().
 *
 *  \par Usage
 *
 *  -# Configure the System Tick with TimeTick_Configure() when MCK changed
 *     \note
 *     Must be done before any invoke of GetTickCount(), Wait() or Sleep().
 *  -# Uses GetTickCount to get current tick value.
 *  -# Uses Wait to wait several ms.
 *  -# Uses Sleep to enter wait for interrupt mode to wait several ms.
