identifiers for general−purpose two, four or eight bytes
writing frames. If dynamic identifiers are used for other
purposes, this is acknowledged. Some frames implement a
<Broad> bit that allows addressing a command to all the
AMIS−30621 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.

Note: Bit 5 and bit 4 in byte 0 indicate the number of data bytes.

Application Commands
GetActualPos
to get the actual position of the stepper−motor. This 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 described 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.
GetActualPos corresponds to the following LIN reading
frames.
