3.2中斷設置
/ A9 w! |* z/ n! |5種不同類型的可編程中斷。當相應的(中斷)準則有效時,中斷引腳被一個高電平觸發。所有的中斷準則都是相結合的(combined ),而且可以用布爾<OR>條件來( Boolean <OR> condition)驅動中斷緩沖器。% t/ ~/ g1 d6 ], M4 R

中斷準則使用的數字代碼來自數字濾波器輸出。因此所有閾值的設置都由量程選擇開關來界定(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)相當于1毫秒, timiming的準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規則的timiming正比于帶寬設置(section 3.1.3 )
