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,中斷引腳被一個高電平觸發(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)動中斷緩沖器。

中斷的產(chǎn)生可能被EEPROM ,image或其他控制位的改變所改變.因為其中一些控制位影響中斷計算。因此,未寫的(中斷)時間序列應(yīng)該在微處理器被其他中斷觸發(fā)(生效)前發(fā)生,或者微處理器應(yīng)該屏蔽(后來發(fā)生的)中斷當(dāng)已寫(中斷)時間序列(write sequences)正在運行時。

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是絕對值( HG_dur和LG_dur寄存器的一個最小可分辨信號(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 )7 k7 r2 L- |/ W
