acceleration or deceleration.

<StepLoss> and <Stall> flags are set. These flags can
only be reset by sending a GetFullStatus command.

<Steploss> flag will be set. The position in the internal
counter will be copied to the <ActPos> register. All flags
can be read out with the GetStatus or GetFullStatus
command.
Important Remark (limited to motion detection flags /
parameters):
flags:
<DelStallLo> and <DelStallHi>. New positioning is
possible and the <ActPos> register will be further updated.
<Steploss> flag. The <Stall>, <AbsStall>,
<DelStallLo> and <DelStallHi> flags are NOT
cleared. New positioning is possible and the <ActPos>
register will be further updated.
<AbsThr[3:0]> and <DelThr[3:0]> are zero. Both
levels can be programmed using the LIN command
SetStallParam in the registers <AbsThr[3:0]> and
<DelThr[3:0]>.
<AbsThr[3:0]> and <DelThr[3:0]> can be set
using the LIN command SetOTPParam. These values are
copied in the RAM registers during power on reset.
