SetMotorParam
This command is provided to the circuit by the LIN master
to set the values for the stepper motor parameters (listed
below) in RAM. Refer to RAM Registers to see the meaning
of the parameters sent by the LIN master.
Important : If a SetMotorParam occurs while a motion
is ongoing, it will modify at once the motion parameters (see
Position Controller). Therefore the application should not
change other parameter than <Vmax> while a motion is
running, otherwise correct positioning cannot be
guaranteed.
SetMotorParam corresponds to the following LIN writing frame with 0x3C identifier (type #4).

SetOTPparam
This command is provided to the circuit by the LIN master
to program the content D[7:0] of the OTP memory byte
OTPA[2:0] and to zap it.
Important: This command must be sent under a specific V BB
voltage value. See parameter V BBOTP in DC Parameters.
This is a mandatory condition to ensure reliable zapping.
SetMotorParam corresponds to a 0x3C LIN writing frames (type #4).
