GetOTPparam
This command is provided to the circuit by the LIN master after a preparation frame (see Preparing frames) was issued, to read the
content of an OTP memory segment which address was specified in the preparation frame.
GetOTPparam
corresponds to a LIN in-frame response with 0x3D indirect ID.

According to parity computation.
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 two data bytes LIN in-frame response with a direct ID (type #5).
