system clock driver

基本解释

Samsung released all BSP package did not separate the PWM as an independent device driver to come out, but only to the operating system used to dispatch the mission to provide the clock source.
三星发布的所有BSP包中都没有单独把PWM作为一个独立设备驱动给出来，而只是拿来给操作系统的任务调度提供时钟源。
The software of system can divide into: initialization module, circulative display module, interrupting module, LED driver module, read clock and write clock module, keyboard and display module.
在已选器件基础上，将整个控制系统程序按功能分为芯片初始化模块、红绿灯循环显示模块、中断处理模块、LED驱动模块、读时钟及写时钟模块、键盘及显示模块。
