SoftStop
stepper motor, it provokes an immediate deceleration to
Vmin (see Minimum Velocity) followed by a stop,
regardless of the position reached. Once the motor is
stopped, TagPos register is overwritten with value in
ActPos register to ensure keeping the stop position.
Note: The dynamic ID allocation has to be assigned to
‘General Purpose 2 Data bytes’ ROM pointer ‘0000’. The
command is decoded only from the command data.
Where:
TestBemf
LIN Master in order to output the Bemf integrator output to
the SWI output of the chip. Once activated, it can be stopped
only after POR. During the Bemf observation, reading of the
SWI state is internally forbidden.

If a SoftStop command occurs during a motion of the
(*) according to parity computation
Broad: If broad = ‘0’ all the stepper motors connected to the LIN bus will stop with deceleration.
This command is provided to the circuit by the
(*) according to parity computation
Broad: If broad = ‘0’ all the stepper motors connected to the LIN bus will be affected.

Note: A SoftStop command occurring during a
DualPosition sequence is not taken into account.
Command SoftStop occurs in the following cases:
•
•
Note: The dynamic ID allocation has to be assigned to
‘General Purpose 2 Data bytes’ ROM pointer, i.e. ‘0000’.
The command is decoded only from the command data.
TestBemf corresponds to the following LIN writing frames
(type #1).

The chip temperature rises above the thermal shutdown
threshold (see DC Parameters and Temperature
Management);
The LIN master requests a SoftStop. Hence
SoftStop will correspond to the following two data
bytes LIN writing frame (type #1).
