32 / 42 page ![]() Register description LIS331DL 32/42 7.13 FF_WU_DURATION_1 (33h) Duration register for Free-Fall/Wake-Up interrupt 1. Duration step and maximum value depend on the ODR chosen. Step 2.5 msec, from 0 to 637.5 msec if ODR=400 Hz, else step 10 msec, from 0 to 2.55 sec when ODR=100 Hz. The counter used to implement duration function is blocked when LIR=1 in configuration register and the interrupt event is verified 7.14 FF_WU_CFG_2 (34h) Table 36. FF_WU_DURATION_1 register D7 D6 D5 D4 D3 D2 D1 D0 Table 37. FF_WU_DURATION_1 description D7-D0 Duration value. Default value: 0000 0000 Table 38. FF_WU_CFG_2 register AOI LIR ZHIE ZLIE YHIE YLIE XHIE XLIE Table 39. FF_WU_CFG_2 description AOI And/Or combination of Interrupt events. Default value: 0 (0: OR combination of interrupt events; 1: AND combination of interrupt events) LIR Latch Interrupt request into FF_WU_SRC_2 reg with the FF_WU_SRC_2 reg cleared by reading FF_WU_SRC_2 reg. Default value: 0 (0: interrupt request not latched; 1: interrupt request latched) ZHIE Enable interrupt generation on Z High event. Default value: 0 (0: disable interrupt request; 1: enable interrupt request on measured accel. value higher than preset threshold) ZLIE Enable interrupt generation on Z Low event. Default value: 0 (0: disable interrupt request; 1: enable interrupt request on measured accel. value lower than preset threshold) YHIE Enable interrupt generation on Y High event. Default value: 0 (0: disable interrupt request; 1: enable interrupt request on measured accel. value higher than preset threshold) YLIE Enable interrupt generation on Y Low event. Default value: 0 (0: disable interrupt request; 1: enable interrupt request on measured accel. value lower than preset threshold) XHIE Enable interrupt generation on X High event. Default value: 0 (0: disable interrupt request; 1: enable interrupt request on measured accel. value higher than preset threshold) XLIE Enable interrupt generation on X Low event. Default value: 0 (0: disable interrupt request; 1: enable interrupt request on measured accel. value lower than preset threshold) |
