    In broadcast mode, the master can send a request to all slaves.
    No response is returned to broadcast requests sent by the master. The broadcast requests are necessarily writing commands. All devices MUST accept the broadcast for writing function. The address 0 is reserved to identify a broadcast exchange.

    What do you think would happen if all slave devices replied to a broadcast request over the same line at the same time?
