/************************************************************
ACC累加器=A
ACC.0=E0H
ACC.0就是ACC的第0位。Acc可以位尋址。
累加器ACC是一個(gè)8位的存儲(chǔ)單元，是用來(lái)放數(shù)據(jù)的。但是，這個(gè)存儲(chǔ)單元有其特殊的地位，
是單片機(jī)中一個(gè)非常關(guān)鍵的單元，很多運(yùn)算都要通過(guò)ACC來(lái)進(jìn)行。以后在學(xué)習(xí)指令時(shí)，
常用A來(lái)表示累加器。但有一些地方例外，比如在PUSH指令中，就必須用ACC這樣的名字。
一般的說(shuō)法，A代表了累加器中的內(nèi)容、而ACC代表的是累加器的地址。
