Register description

7.11
FF_WU_SRC_1 (31h)
Free-fall and wake-up source register. Read only register.
Reading at this address clears FF_WU_SRC_1 register and the FF, WU 1 interrupt and
allows the refreshment of data in the FF_WU_SRC_1 register if the latched option was
chosen.
7.12
FF_WU_THS_1 (32h)
Most significant bit (DCRM) is used to select the resetting mode of the duration counter. If
DCRM=0 counter is resetted when the interrupt is no more active else if DCRM=1 duration
counter is decremented.
