MCS-52单片机的捕捉功能及应用

The Capture Function and Application of MCS-52 Single-chip Computers

ＭＣＳ－５２系列单片机的Ｔ２定时器具有捕捉、自动重装载和波特率发生器三种操作方式， 其捕捉功能在一般的单片机资料中介绍得很少， 但在单片机实际应用中， 使用捕捉功能能使编程更简单， 应用更灵活。

The T2 Timer of MCS-52 series Single-chip Computers has three manipulation modes which include capture function, automatically loading again and Baud rate producer, but the capture function is seldom introduced in the books on Single-chip Computers. In practical application of Single-chip Computers, the use of capture function can make programming easier and application much more flexible.
