FF_WU_SRC_2 (35h)
Table 40.
Table 41.
Free-fall and wake-up source register. Read only register.
Reading at this address clears FF_WU_SRC_2 register and the FF_WU_2 interrupt and
allows the refreshment of data in the FF_WU_SRC_2 register if the latched option was
chosen.
FF_WU_THS_2 (36h)
Table 42.
Table 43.
Most significant bit (DCRM) is used to select the resetting mode of the duration counter. If
DCRM=0 counter is reset when the interrupt is no more active else if DCRM=1 duration
counter is decremented.
