Five different types of interrupts can be programmed. When the corresponding criterion , t/ s# q2 I2 O# T7 \* z
becomes valid, the interrupt pin is triggered to a high level. All interrupt criteria are combined $ S X6 \3 Q1 O2 M( D2 p

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。

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!!! |
