(3)时钟振荡电路:用来产生微控制器工作时的时钟信号,可理解为整个控制系统工作的“节拍”信号,类似于电视接收中的行、场同步信号。它是指挥微处理器 TMP87CS38N 的信号,它保证微处理器执行程序的准确性,使各种控制功能正常作用。时钟振荡电路由微处理器 TMP87CS38N(31)、(32)脚的内部电路及外围的12MHz 晶振、移相电容共同组成。振荡电路输出的时钟振荡信号提供给微处理器作为时钟脉冲信号。(4)存储器:用来存储微控制器工作的程序和一些固定的或需要处理的数据。由于存储器的支持,微处理器可以脱离人的直接干预,而自动地有条不紊地 (3) clock oscillation circuit: used to generate the microcontroller clock signal can be understood as the work of the entire control system “beat” signal, similar to the television receiving line and field synchronization signal. It is the command microprocessor TMP87CS38N signal, which guarantees the accuracy of the microprocessor to perform the program, so that a variety of control functions normal role. Clock oscillation circuit by the microprocessor TMP87CS38N (31), (32) feet of the internal circuit and the external 12MHz crystal, phase shift capacitors together. Oscillator output clock oscillation signal is provided to the microprocessor as a clock signal. (4) memory: used to store the microcontroller work procedures and some fixed or need to deal with the data. Because of the memory support, the microprocessor can automatically and methodically
