ASAP2 / A2L file: COM_AXIS vs STD_AXIS

Hello,

I would like to know, in which cases the Embedded Coder generates axis of look-up tables as STD_AXIS or COM_AXIS.

Does the Embedded Coder check, if the axes are used more than once? Or does it depend on the kind of initialization of the Simulink.Parameter objects, e.g.

    x,   y,   z as individual variables => COM_AXIS?
  A.x, A.y, A.z as structure  variable  => STD_AXIS?

Thanks in advance and best regards

Thomas
