Funktion 02

: 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.
