c51(用于单片机开发的一种c语言)的头文件。类似于头文件AT89X52.h。这两个头文件基本是一样的，只是在使用时对位的定义不一样，at89x52.h文件中对P1.1的操作是写成P1_1；reg52.h文件中的操作则写成P1^1。表示方法不一样而已。另外前者是特指ATMEL公司的52系列单片机，后者指所有52系列的单片机。 Table of Contents reg51.h reg52.h reg51.h /*-------------------------------------------------------------------------- REG51.H Header file for generic 80C51 and 80C31 microcontroller.
