Two different types of frames can be transmitted:
I
-frames and
transparent frames

For
I
-frames (command XIF via CMDR register), the address and control fields are generated
autonomously by the HSCX and the data in the XFIFO is entered into the information field of
the frame. This is possible only, if the HSCX is operated in the auto-mode.
For transparent frames (command XTF via CMDR register), the address and the control fields
have to be entered in the XFIFO as well. This is possible in all operating modes and used also
in auto-mode for sending U-frames.
