單片機(jī)中定時(shí)計(jì)數(shù)器的應(yīng)用情況

作者：時(shí)間：2016-11-26 來源：網(wǎng)絡(luò)

在單片機(jī)的定時(shí)計(jì)數(shù)器應(yīng)用中對(duì)程序的初始化過程要完成如下的工作：

1、對(duì)TMOD賦值，以確定T0和T1的工作方式

2、計(jì)算初值，并將其寫入TH0和TL0或TH1；TL1中

3、中斷方式時(shí)，則對(duì)IE賦值，開放中斷：EA，ET0；ET1

4、使TR0或TR1置為，啟動(dòng)定時(shí)計(jì)數(shù)器定時(shí)或計(jì)數(shù)
