Data Sheet
GetFullStatus
This command is provided to the circuit by the LIN Master
to get a complete status of the circuit and of the Stepper-
motor. Refer to § 0 and § 9.2.2.10 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.

Important
It is not mandatory for the LIN Master to initiate the second
in-frame response if ActPos, TagPos and SecPos are not
needed by the application.
