SetPosition
This command is provided to the circuit by the Master to the motors to a given position relative to the zero
position, defined in number of half or micro steps, according to StepMode[1:0] value.
SetPosition will not be performed if one of the following flags is set to one:
• temperature shutdown <TSD>
• under voltage <UV2>
• step loss <StepLoss>
• electrical defect <ElDef>

SoftStop
If a SoftStop command occurs during a motion of the Stepper motor, it provokes an immediate deceleration to
Vmin followed by a stop, regardless of the position reached. This command occurs in the following cases:
• The chip temperature raises the Thermal shutdown threshold.
• The Master requests a SoftStop.
