flat_hy<2:0>
reserved: write ‘0’
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
