16.2 Application Commands
GetActualPos
This command is provided to the circuit by the LIN master 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 LSBs 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 GetActualPosition command will not attempt to reset any flag. GetActualPos corresponds to the following LIN reading frames.
1) Four data bytes in-frame response with direct ID (type #5)
Where:
(*)
According to parity computation.
ID[5:0]:
Dynamically allocated direct identifier. There should be as many dedicated identifiers to this
GetActualPos command as there are stepper-motors connected to the LIN bus.
2) One preparing frame prior four data bytes in-frame response with 0x3D indirect ID

GetFullStatus
This command is provided to the circuit by the LIN master to get a complete status of the circuit and the stepper motor. Refer to RAM
Registers and Flags Table to see the meaning of the parameters sent to the LIN master.
Note:
A GetFullStatus command will attempt to reset flags <TW>, <TSD>, <UV2>, <ElDef>, <StepLoss>, <CPFail>, <OVC1>,
<OVC2> and <VddReset>.
GetFullStatus
corresponds to two successive LIN in-frame responses with 0x3D indirect ID.
