flat_hold_time<1:0>: delay time for which the flat value must remain stable for the flat interrupt
to be generated: ´00b´ 0 ms, ´01b´ 512 ms, ´10b´ 1024 ms,
´11b´ 2048 ms
flat_hy<2:0>:
defines flat interrupt hysteresis; flat value must change by more than twice
the value of flat interrupt hysteresis to detect a state change. For details see
chapter 4.7.8.
‘000b’ hysteresis of the flat detection disabled
