中断的产生可能被EEPROM ,image或其他控制位的改变所改变.因为其中一些控制位影响中断计算。因此,未写的(中断)时间序列应该在微处理器被其他中断触发(生效)前发生,或者微处理器应该屏蔽(后来发生的)中断当已写(中断)时间序列(write sequences)正在运行时。- u9 _8 t' g; S- A7 w+ }

中断准则使用的数字代码来自数字滤波器输出。因此所有阈值的设置都由量程选择开关来界定(section 3.1.3.2 ) 。用于高加速度和低加速度之间的去抖timiming是绝对值( HG_dur和LG_dur寄存器的一个最小可分辨信号(correspond to)相当于1毫秒, timiming的准确性于振荡器精度成正比= + / -10 % ) , 因此,它并不依赖于选定的带宽。用于motion中断位和alert规则的timiming正比于带宽设置(section 3.1.3 )
