The user could use the possible addresses above to select
slave 3 only. Another combination could be to select slave 2
and 3 only as shown below.
More than one slave may have the same SADDR address
as well, and a given address could be used to modify the
address so that it is unique.
6.1.2.2 Using the Broadcast Address to Select Slaves
Using the broadcast address, the master can communicate
with all the slaves at once. It is formed by performing a logi-
cal OR of SADDR and SADEN with 0s in the result treated
as “don’t cares”.
“Don’t cares” allow for a wider range in defining the broad-
cast address, but in most cases, the broadcast address will
be FFH.
On reset, SADDR and SADEN are “0”. This produces an
given address of all “don’t cares” as well as a broadcast
address of all “don’t cares.” This effectively disables Auto-
matic Addressing mode and allows the microcontroller to
function as a standard 8051, which does not make use of
this feature.
