33 / 38 page ![]() LIS331DL Register description 33/38 7.17 FF_WU_DURATION_2 (37h) Duration register for Free-Fall/Wake-Up interrupt 2. Duration step and maximum value depend on the ODR chosen. Step 2.5 msec, from 0 to 637.5 msec if ODR=400Hz, else step 10 msec, from 0 to 2.55 sec when ODR=100Hz. The counter used to implement duration function is blocked when LIR=1 in configuration register and the interrupt event is verified. 7.18 CLICK_CFG (38h) Table 38. FF_WU_DURATION_2 register D7 D6 D5 D4 D3 D2 D1 D0 Table 39. FF_WU_DURATION_2 description D7-D0 Duration value. Default value: 0000 0000 Table 40. CLICK_CFG register - LIR Double_Z Single_Z Double_Y Single_Y Double_X Single_X Table 41. CLICK_CFG description LIR Latch Interrupt request into CLICK_SRC reg with the CLICK_SRC reg refreshed by reading CLICK_SRC reg. Default value: 0 (0: interrupt request not latched; 1: interrupt request latched) Double_Z Enable interrupt generation on double click event on Z axis. Default value: 0 (0: disable interrupt request; 1: enable interrupt request) Single_Z Enable interrupt generation on single click event on Z axis. Default value: 0 (0: disable interrupt request; 1: enable interrupt request) Double_Y Enable interrupt generation on double click event on Y axis. Default value: 0 (0: disable interrupt request; 1: enable interrupt request) Single_Y Enable interrupt generation on single click event on Y axis. Default value: 0 (0: disable interrupt request; 1: enable interrupt request) Double_X Enable interrupt generation on double click event on X axis. Default value: 0 (0: disable interrupt request; 1: enable interrupt request) Single_X Enable interrupt generation on single click event on X axis. Default value: 0 (0: disable interrupt request; 1: enable interrupt request) Table 42. Axis Double_Z / Y / X Single_Z / Y / X Click output 00 0 0 1 Single |
