*
* \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.
