interrupt servicing system 中断响应系统
The program design is based on bus time sharing and interrupt servicing. It can renew the speeds and the directions of every motor at real time.
程序设计基于中断服务和总线分时复用方式，实时更新各个电机的速度和方向。
In other words, an FIQ is just a higher priority interrupt request, that is prioritized by disabling IRQ and other FIQ handlers during request servicing.
在换句话说，一个FIQ仅仅是一个更高优先级的中断请求时，由请求服务期间禁用IRQ和其他FIQ处理程序的优先级。
