Funktion 02h : Code word request
After each reset the code word is transmitted through the handshake channels by
the C1300 module. This is done without setting the data valid bit. The code word
is used to report that the C1300 module is initialized and ready to work to the
VME system. At any time the code word can be requested by function 02h.
