The following examples will help to show the versatility of this scheme.
Example 1, slave 0:
(4)
Example 2, slave 1:
(5)
In the above example SADDR is the same and the SADEN data is used to differentiate
between the two slaves. Slave 0 requires a ‘0’ in bit 0 and it ignores bit 1. Slave 1 requires
a ‘0’ in bit 1 and bit 0 is ignored. A unique address for Slave 0 would be 1100 0010 since
slave 1 requires a ‘0’ in bit 1. A unique address for slave 1 would be 1100 0001 since a ‘1’
in bit 0 will exclude slave 0. Both slaves can be selected at the same time by an address
which has bit 0 = 0 (for slave 0) and bit 1 = 0 (for slave 1). Thus, both could be addressed
with 1100 0000.
