StepMode
Shaft
SecPos[10:0]Secure Position of the stepper-motor. This is the position to which the motor is driven in case of a LIN communication

Current amplitude value to be fed to each coil of the stepper-motor. The table below provides the 16 possible values
for IRUN.
Hold current for each coil of the stepper-motor. The table below provides the 16 possible values for IHOLD.
Indicator of stepping mode to be used.
Indicator of Reference Position. If Shaft = ‘0’, the reference position is the maximum inner position, whereas if
Shaft = ‘1’, the reference position is the maximum outer position
loss or when the LIN error counter overflows. If SecPos[10:0] = “100 0000 0000”, this means that Secure Position
is disabled, e.g. the stepper-motor will be kept in the position occupied at the moment these events occur.
The Secure Position is coded on 11 bits only, providing actually the most significant bits of the position, the non coded
least significant bits being set to ‘0’.
