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 loss or when
the LIN error−counter overflows. If
<SecPos[10:0]> = “100 0000 0000”,
secure positioning is disabled; 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’.
