74LS393和Intel8253中断应用
采用74LS393对实验箱中8MHz时钟进行分频处理，从中获得低于2MHz的时钟信号￠，并将时钟信号￠输入给Intel8253的某通道C。要求通道C的输出信号作为Intel8259的可屏蔽中断请求IRQ2，使得中央处理器每隔2秒钟中断一次，中断程序将中断次数采用二进制方式在8个发光二极管中显示出来-74LS393 and 74LS393 used Intel8253 interruption of the application of the experimental box 8MHz clock frequency to deal with less than 2MHz gain ￠ of the clock signal and clock signal input to the Intel8253 ￠ a channel C. Requirements of channel C of the output signal as Intel8259 maskable interrupt request can be IRQ2, allows the CPU interrupt once every 2 seconds, interrupt procedure will interrupt the use of a binary number of 8 in the light-emitting diode shown
