Example 2, slave 1:

Example 2, slave 2:
(8)
In the above example the differentiation among the 3 slaves is in the lower 3 address bits.
Slave 0 requires that bit 0 = 0 and it can be uniquely addressed by 1110 0110. Slave 1
requires that bit1=0 and it can be uniquely addressed by 1110 0101. Slave 2 requires
that bit 2 = 0 and its unique address is 1110 0011. To select Slaves 0 and 1 and exclude
Slave 2 use address 1110 0100, since it is necessary to make bit 2 = 1 to exclude slave 2.
The Broadcast Address for each slave is created by taking the logical OR of SADDR and
SADEN. Zeros in this result are treated as don’t-cares. In most cases, interpreting the
don’t-cares as ones, the broadcast address will be FF hexadecimal. Upon reset SADDR
and SADEN are loaded with 0s. This produces a given address of all ‘don’t cares’ as well
as a Broadcast address of all ‘don’t cares'. This effectively disables the Automatic
Addressing mode and allows the microcontroller to use standard UART drivers which do
not make use of this feature.
6.11 Interrupt priority and polling sequence
The device supports six interrupt sources under a four level priority scheme. Table 24
summarizes the polling sequence of the supported interrupts. (See Figure 19).
SADDR = 1100 0000
SADEN = 1111 1001
Given = 1100 0XX0
----------------------------------------------------
SADDR = 1110 0000
SADEN = 1111 1010
Given = 1110 0X0X
----------------------------------------------------
SADDR = 1100 0000
SADEN = 1111 1100
Given = 1100 00XX
----------------------------------------------------
