PIC 單片機(jī)的組成習(xí)題解答 解答部分1. PIC 單片機(jī)指令的執(zhí)行過程遵循著一種全新哈佛總線體系結(jié)構(gòu)的原則，充分利用了計算機(jī)系統(tǒng)在程序存儲器和數(shù)據(jù)存儲器之間地址空間的相互獨立性，取指過程和執(zhí)行指令過程可以流水線操作同時進(jìn)行。因此，當(dāng)PIC 時鐘頻率為4MHZ時，執(zhí)行一條非轉(zhuǎn)移類指令需要4 個系統(tǒng)時鐘周期，即1us,但其指令執(zhí)行的真實時間應(yīng)為2us(在執(zhí)行n—1 條指令時取第n 條指令，然后執(zhí)行第n 條指令)。所以選項B 正確2. 端口RE 共有3 個引腳RE0~RE2，它們除了用做普通I/O 引腳和第5~7 路模擬信號輸入引腳外，還依次分別承擔(dān)并行口讀出/寫入/片選控制端引腳。A． 對。讀出/寫入（REO~RE1）。B．錯。同步串行的相關(guān)引腳與端口C 有關(guān)。C．錯。通用異步/同步串行的相關(guān)引腳與端口C有關(guān)。D． 錯。CCP模塊的相關(guān)引腳也是與端口C有關(guān)。所以選項A正確。3. 上電延時電路能提供一個固定的72ms 上電延時，從而使VDD有足夠的時間上繁榮昌盛到單片機(jī)合適的工作電壓。所以選項B 正確。

單片機(jī)I/O口的使用:對單片機(jī)的控制，其實就是對I/O口的控制，無論單片機(jī)對外界進(jìn)行何種控制，亦或接受外部的控制，都是通過I/O口進(jìn)行的。單片機(jī)總共有P0、P1、P2、P3四個8位雙向輸入輸出端口，每個端口都有鎖存器、輸出驅(qū)動器和輸入緩沖器。4個I/O端口都能作輸入輸出口用，其中P0和P2通常用于對外部存儲器的訪問。§4.1 MCS-51單片機(jī)的并行端口結(jié)構(gòu)與操作 51系列單片機(jī)有4個I/O端口，每個端口都是8位準(zhǔn)雙向口，共占32根引腳。每個端口都包括一個鎖存器(即專用寄存器P0～P3)、一個輸出驅(qū)動器和輸入緩沖器。通常把4個端口籠統(tǒng)地表示為P0～P3。
