Five different types of interrupts can be programmed. When the corresponding criterion ; K2 a; E$ o' p
becomes valid, the interrupt pin is triggered to a high level. All interrupt criteria are combined 9 R& l5 L* u( b% j

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。0 ?5 P2 {) A: b9 [

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。

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 )

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!!! |
