【文章內(nèi)容簡介】 view as an 8bit variable called 39。register39。, each bit being connected to a different Input/Output pin. 每個(gè)港口有 8個(gè)引腳，并且將被視為從軟件的角度來看，這是 8位變量稱為 39。登記 39。 ，每個(gè)位被連接到不同的輸入 /輸出引腳。 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. 您也可以通知兩個(gè)不同類型的存儲(chǔ)器： RAM 和 EEPROM 的。不久， RAM 是用來存儲(chǔ)變量在程序執(zhí)行，而 EEPROM 存儲(chǔ)器是用來存儲(chǔ)程序本身，這就是為什么它常常被稱為 39。程序存儲(chǔ)器。記憶組 織將詳細(xì)討論后。 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
