AMIS-30623 LIN Microstepping Motordriver
GetOTPparam
This command is provided to the circuit by the LIN master after a preparation frame (see
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.
GetStatus
This command is provided to the circuit by the LIN master to get a quick status (compared to that of
circuit and of the stepper-motor. Refer to
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).

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.
