Detailed Description

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().

Usage

1. Configure the System Tick with TimeTick_Configure() when MCK changed

   Note:

   Must be done before any invoke of GetTickCount(), Wait() or Sleep().

2. Uses GetTickCount to get current tick value.
3. Uses Wait to wait several ms.
4. Uses Sleep to enter wait for interrupt mode to wait several ms.

Definition in file timetick.h.
