GetStatus
This command is provided to the circuit by the LIN master
to get a quick status (compared to that of GetFullStatus
command) of the circuit and of the stepper−motor. Refer to
Flags Table to see the meaning of the parameters sent to the
LIN master.
Note: A GetStatus command will attempt to reset flags
<TW>, <TSD>, <UV2>, <ElDef>, <StepLoss> and
<VddReset>.
GetStatus corresponds to a 2 data bytes LIN in−frame response with a 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 GetStatus command
as there are stepper−motors connected to the LIN bus.
GotoSecurePosition
This command is provided by the LIN master to one or all
of the stepper−motors to move to the secure position
<SecPos[10:0]>. It can also be internally triggered if
the LIN bus communication is lost, after an initialization
phase, or prior to going into sleep mode. See the priority
encoder description for more details. The priority encoder
table also acknowledges the cases where a
GotoSecurePosition command will be ignored.
Note: The dynamic ID allocation has to be assigned to
‘General Purpose 2 Data bytes’ ROM pointer, i.e. ‘0000’.
The command is decoded only from the command data.
