Special Addresses
Addresses $F0 through $FF are reserved for special functions with address
$F0 used as a broadcast address.
Address $F0
Node address $F0 is used as a single point address, i.e. it is intended for
use in configurations with a single slave. The slave will respond to all
messages with node address $F0. You must be careful to prevent multiple
slaves from receiving commands with the broadcast address as this will
cause a bus contention.
De ned Commands (master to slave)
There are a total of nine commands that can be issued from the master.
These are listed in the Figure 5-5.
