8051单片机外文翻译资料内容摘要：
view as an 8bit variable called 39。 register39。 , each bit being connected to a different Input/Output pin. 每个港口有 8个引脚，并且将被视为从软件的角度来看，这是 8位变量称为 39。 登记 39。 ，每个位被连接到不同的输入 /输出引脚。 You can also notice two different memory types: RAM and EEPROM. Shortly, RAM is used to store variable during program execution, while the EEPROM memory is used to store the program itself, that39。 s why it is often referred to as the 39。 program memory39。 . The memory anization will be discussed in detail later. 您也可以通知两个不同类型的存储器： RAM 和 EEPROM 的。 不久， RAM 是用来存储变量在程序执行，而 EEPROM 存储器是用来存储程序本身，这就是为什么它常常被称为 39。 程序存储器。 记忆组 织将详细讨论后。 The special features of the 89S52 microcontroller are grouped in the blue box at the bottom of figure . At this stage of the tutorial, it is just important to note that the 89S52 incorporates hardware circuits that can be used to prevent the processor from executing various repetitive tasks and save processing power for more plex calculations. Those simple tasks can be counting the number of external p。阅读剩余 0%
