5种不同类型的可编程中断。当相应的(中断)准则有效时,中断引脚被一个高电平触发。所有的中断准则都是相结合的(combined ),而且可以用布尔<OR>条件来( Boolean <OR> condition)驱动中断缓冲器。

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 ), V! _" Q; a p1 [7 l9 I) R* L

这是本人接的一个翻译活,不算什么机密,共40页,但是还没翻完,先看十页吧.发出来就是让大家看看mens系统的陀螺仪是怎么工作的!!!有兴趣的话,可以十天后下我的完整版的数据表!!! |
