addressing a command to all the AMIS−30623 circuits
connected to the same LIN bus. <Broad> is active when at
‘0’, in which case the physical address provided in the frame
is thus not taken into account by the slave nodes.
Application Commands

to get the actual position of the stepping−motor. This
GetActualPos corresponds to the following LIN reading
frames.

position (<ActPos[15:0]>) is returned in signed two’s
complement 16−bit format. One should note that according
to the programmed stepping mode, the LSB’s of
<ActPos[15:0]> may have no meaning and should be
assumed to be ‘0’, as prescribed in Position Ranges.
GetActualPos also provides a quick status of the circuit
and the stepper−motor, identical to that obtained by
command GetStatus (see further).
Note: A GetActualPos command will not attempt to
reset any flag.
