時(shí)鐘和定時(shí)器

CPU提供的時(shí)鐘和計(jì)時(shí)器包括逝去時(shí)間時(shí)鐘，當(dāng)前時(shí)間時(shí)鐘和軟/硬件看門狗定時(shí)器。關(guān)于CPU提供的定時(shí)器函數(shù)和定時(shí)結(jié)點(diǎn)，詳見第八章“定時(shí)器和計(jì)數(shù)器”

逝去時(shí)間時(shí)鐘

逝去時(shí)間時(shí)鐘記錄的是CPU通電至目前的時(shí)間間隔，發(fā)生電源故障此數(shù)據(jù)不會(huì)保持，每次上電這個(gè)時(shí)鐘都會(huì)回0并重新計(jì)時(shí)。從這個(gè)時(shí)鐘開始計(jì)時(shí)到時(shí)鐘計(jì)時(shí)計(jì)時(shí)值自動(dòng)回0(中間沒有電源故障或停/上電情況，到秒)的時(shí)間間隔大約為100年。因?yàn)槭湃r(shí)間時(shí)鐘為系統(tǒng)軟件操作和定時(shí)器功能塊提供了時(shí)間基準(zhǔn)，所以不能在編程器或用戶程序中將其重啟。然而，用戶程序可以使用服務(wù)請(qǐng)求16和服務(wù)請(qǐng)求50讀取逝去時(shí)間時(shí)鐘，這個(gè)命令可以提供更高的時(shí)鐘分辨率。

當(dāng)前時(shí)間時(shí)鐘

硬件的當(dāng)前時(shí)間時(shí)鐘保存了CPU的當(dāng)前時(shí)間。當(dāng)前時(shí)間時(shí)鐘支持以下7種功能:

■年(2位)

■月

■日

■小時(shí)分鐘

■秒

■星期幾

當(dāng)前時(shí)間時(shí)鐘以電池為后備電源，發(fā)生外部電源故障時(shí)不會(huì)清零?？梢允褂镁幊誊浖?nèi)的服務(wù)請(qǐng)求函數(shù)7讀取/設(shè)定時(shí)間和日期。

當(dāng)前時(shí)間時(shí)鐘可以自動(dòng)處理年與年之間，月與月之間的時(shí)間轉(zhuǎn)換，并且可以自動(dòng)補(bǔ)償閏年月，一直至2036年。
