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