设计一个汽车尾灯控制器，实现对汽车尾灯显示状态的控制。在汽车尾部左右两侧各有3个指示灯（假定采用发光二极管模拟），根据汽车运行情况，指示灯具有4种不同的显示模式：（1）汽车正向行驶时，左右两侧的指示灯全部处于熄灭状态；（2）汽车右转弯行驶时，右侧的3个指示灯按右循环顺序点亮；（3）汽车左转弯行驶时，左侧3个指示灯按左循环顺序电亮；（4）汽车临时刹车时，左右两侧的指示灯同时处于闪烁状态。-Design a car taillight controller to realize the car taillight display state control. In the automobile tail lights on each side 3 (assuming the use of simulated light-emitting diode), according to auto operation, the light has 4 different display modes: (1) car moving forward, left and right sides of the light All in the off state　(2) driving cars turn right, the right of the press the right light cycle sequence of 3 lit　(3) when the vehicle left turn traffic, left three light left-loop sequence of electric light　(4) Auto temporary brake, left and right at the blinking light while state.
