DI232巴赫曼
DI232有三種基本的I/O操作形式：查詢(xún)、中斷、塊操作。這三種I/O操作在初始化和數(shù)據(jù)傳送時(shí)涉及到寄存器操作。
查詢(xún)方式依靠軟件查詢(xún)串行控制器，從而決定什么時(shí)候數(shù)據(jù)應(yīng)從串行控制器輸入或輸出。在此模式中，主中斷使能位和WAIT/DMA請(qǐng)求位都應(yīng)編程為0，從而清除任何中斷或DMA請(qǐng)求。查詢(xún)是通過(guò)對(duì)RR0的狀態(tài)檢測(cè)進(jìn)行的。在此模式中，中斷功能失效。在轉(zhuǎn)入數(shù)據(jù)處理前，必須對(duì)RR0讀分析，以決定進(jìn)入怎樣的例程。
中斷方式中，串行控制器的每一個(gè)通道包括三個(gè)中斷源：接收器中斷、發(fā)送器中斷和外部/狀態(tài)中斷。
塊操作方式可將W/REQ輸出與WR1中的就緒/請(qǐng)求位配合。通過(guò)編程，W/REQ輸出在塊操作方式中能被定義為WAIT信號(hào)，在DMA方式中可作為REQ信號(hào)。
3.2 軟件的編寫(xiě)
不同的應(yīng)用場(chǎng)合，對(duì)Z85C30的初始化流程不同，這就需要對(duì)Z85C30的寫(xiě)寄存器賦予相應(yīng)的初值。
在SCC初始化完成后，即可進(jìn)行通信。傳送緩沖區(qū)和接收緩沖區(qū)全部為空。軟件把第1個(gè)傳送字符寫(xiě)到傳送緩沖器，中斷才會(huì)產(chǎn)生。第1個(gè)傳送字符到了SCC的移位寄存器，傳送中斷產(chǎn)生。然后，SCC繼續(xù)判斷中斷，直到報(bào)文結(jié)束。報(bào)文結(jié)束時(shí)，應(yīng)執(zhí)行復(fù)位發(fā)送中斷賦值命令，用來(lái)禁止發(fā)送請(qǐng)求中斷。SCC檢測(cè)到最后一個(gè)字符，中斷將停止，直到另外的報(bào)文寫(xiě)到傳送緩沖器。
寄存器RR2用來(lái)說(shuō)明中斷矢量和狀態(tài)，它從B信道讀取。RR3是中斷賦值寄存器，用來(lái)指示中斷的類(lèi)型，它從A信道讀取。看網(wǎng)絡(luò)補(bǔ)充版（www.dpj.com.cn）中列出了Z85C30的中斷流程。
外部/狀態(tài)中斷源包括：斷點(diǎn)/異常中斷、發(fā)送欠載/報(bào)文結(jié)束中斷、CTS中斷、同步/搜索中斷、DCD中斷、零計(jì)數(shù)中斷。它由WR1和WR15 設(shè)置，只有WR1中外部/狀態(tài)中斷允許位置和WR15中的相應(yīng)控制位置位后，外部/狀態(tài)條件才會(huì)產(chǎn)生中斷。
