C-bus transmission
the MSB of each word is transmitted first
there is no restriction on the number of words to be transmitted, but if more than five words are requested, the following
content will be “FF” continuously.
Normally every dataline transmission has to be ended with STOP condition by non-acknowledge of the controller.
