5種不同類型的可編程中斷,。當(dāng)相應(yīng)的(中斷)準(zhǔn)則有效時(shí),,中斷引腳被一個(gè)高電平觸發(fā),。所有的中斷準(zhǔn)則都是相結(jié)合的(combined ),,而且可以用布爾<OR>條件來( Boolean <OR> condition)驅(qū)動(dòng)中斷緩沖器,。$ F" V& h- r! F9 n

# m: c: l' o: W# `4 R中斷準(zhǔn)則使用的數(shù)字代碼來自數(shù)字濾波器輸出,。因此所有閾值的設(shè)置都由量程選擇開關(guān)來界定(section 3.1.3.2 ) 。用于高加速度和低加速度之間的去抖timiming是絕對(duì)值( HG_dur和LG_dur寄存器的一個(gè)最小可分辨信號(hào)(correspond to)相當(dāng)于1毫秒,, timiming的準(zhǔn)確性于振蕩器精度成正比= + / -10 % ) ,, 因此,它并不依賴于選定的帶寬,。用于motion中斷位和alert規(guī)則的timiming正比于帶寬設(shè)置(section 3.1.3 )
