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(guò)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(jì)算機(jī)系統(tǒng)在程序存儲(chǔ)器和數(shù)據(jù)存儲(chǔ)器之間地址空間的相互獨(dú)立性，取指過(guò)程和執(zhí)行指令過(guò)程可以流水線操作同時(shí)進(jìn)行。因此，當(dāng)PIC 時(shí)鐘頻率為4MHZ時(shí)，執(zhí)行一條非轉(zhuǎn)移類(lèi)指令需要4 個(gè)系統(tǒng)時(shí)鐘周期，即1us,但其指令執(zhí)行的真實(shí)時(shí)間應(yīng)為2us(在執(zhí)行n—1 條指令時(shí)取第n 條指令，然后執(zhí)行第n 條指令)。所以選項(xiàng)B 正確2. 端口RE 共有3 個(gè)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(hào)輸入引腳外，還依次分別承擔(dān)并行口讀出/寫(xiě)入/片選控制端引腳。A． 對(duì)。讀出/寫(xiě)入（REO~RE1）。B．錯(cuò)。同步串行的相關(guān)引腳與端口C 有關(guān)。C．錯(cuò)。通用異步/同步串行的相關(guān)引腳與端口C有關(guān)。D． 錯(cuò)。ccp模塊的相關(guān)引腳也是與端口C有關(guān)。所以選項(xiàng)A正確。3. 上電延時(shí)電路能提供一個(gè)固定的72ms 上電延時(shí)，從而使VDD有足夠的時(shí)間上繁榮昌盛到單片機(jī)合適的工作電壓。所以選項(xiàng)B 正確。

SPMC65系列單片機(jī)編程指南(中文版):SPMC65X系列是由凌陽(yáng)公司設(shè)計(jì)開(kāi)發(fā)的8位微控制器。每款芯片都獨(dú)具特色，同時(shí)凌陽(yáng)公司還開(kāi)發(fā)了一款仿真芯片ECMC653，專(zhuān)門(mén)用于SPMC65X系列的仿真。采用 SPMC65 CPU 核，凌陽(yáng)公司新開(kāi)發(fā)了功能強(qiáng)大的8位SPMC65系列CPU。該系列CPU 具有可編程的通用I/O端口、不同大小的ROM 和RAM 區(qū)、8位/16位定時(shí)/計(jì)數(shù)器、強(qiáng)大的ccp (Capture/Compare/PWM)功能模塊和看門(mén)狗復(fù)位電路等。并采用先進(jìn)的微米制造工藝，保證了產(chǎn)品高的電磁兼容性和可靠性。除此之外，部分SPMC65X系列芯片具備高吸入電流和慢速輸出的端口、豐富的外部中斷源、低電壓復(fù)位、ADC、PWM、標(biāo)準(zhǔn)通訊接口和多種時(shí)鐘選擇。SPMC65X系列芯片適用于通用工控場(chǎng)合、計(jì)算機(jī)外圍控制和家電等。ECMC653采用8位SPMC65 CPU 核，具有928字節(jié)的RAM 和16k字節(jié)的ROM。同時(shí)還集成了1個(gè)時(shí)基、1個(gè)看門(mén)狗定時(shí)器、6個(gè)16位定時(shí)/計(jì)數(shù)器和9通道的ADC。為了降低整個(gè)仿真板的成本，該芯片還配有一個(gè)OTP ROM 的串行可編程接口。此外，為了幫助用戶加快程序的調(diào)試，并發(fā)現(xiàn)程序中隱藏的錯(cuò)誤，該芯片內(nèi)部專(zhuān)門(mén)有一RAM區(qū)域用于記錄程序最近一段時(shí)間執(zhí)行的指令，用戶可以從中了解到程序是否正確執(zhí)行。

此軟件是PIC單片機(jī)的編程助手軟件，你可以通過(guò)它來(lái)設(shè)定一些內(nèi)部模塊的使用情況(如定時(shí)器，SCI，ccp)等模塊的設(shè)置。省去了人工去記這些設(shè)定值。設(shè)置完成后可以自動(dòng)生成C源程序。
