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(fā)。所有的中斷準則都是相結(jié)合的(combined ),,而且可以用布爾<OR>條件來( Boolean <OR> condition)驅(qū)動中斷緩沖器,。! x0 Y" V( B) ~. K: V

中斷的產(chǎn)生可能被EEPROM ,image或其他控制位的改變所改變.因為其中一些控制位影響中斷計算,。因此,,未寫的(中斷)時間序列應該在微處理器被其他中斷觸發(fā)(生效)前發(fā)生,或者微處理器應該屏蔽(后來發(fā)生的)中斷當已寫(中斷)時間序列(write sequences)正在運行時,。

Interrupt criteria are using digital code coming from digital filter output. As a consequence all

T" B中斷準則使用的數(shù)字代碼來自數(shù)字濾波器輸出,。因此所有閾值的設(shè)置都由量程選擇開關(guān)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(guī)則的timiming正比于帶寬設(shè)置(section 3.1.3 )

這是本人接的一個翻譯活,不算什么機密,共40頁,但是還沒翻完,先看十頁吧.發(fā)出來就是讓大家看看mens系統(tǒng)的陀螺儀是怎么工作的!!!有興趣的話,可以十天后下我的完整版的數(shù)據(jù)表!!! |
