FF_WU_DURATION_2 (37h)
Table 44.
Table 45.
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=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.
