Format  Sint32 CDC_SetFiltRange (Sint32 filtno, Sint32 fad, Sint32 fasnum)
 Input  filtno: Aperture number
:  fad: Start frame address
:  fasnum: Number of frame address sectors (0: There is no valid FAD range)
 Output  None
 Function value  Returns an error code.
 End flag  ESEL flag
 Function  Sets the frame address range for the aperture. When fasnum = 0, FAD range in aperture mode
