BYTE 1, is the Byte Address. The Byte Address identi-
fies a unique address for the Status or Control Regis-
ters as shown in Table 3. The following byte, Byte 2, is
the data byte that is used for READ and WRITE opera-
tions.

Slave Address, Byte Address, and Data Byte
The byte communication format for the serial bus is
shown in Figures 7 and 8 above. The first byte, BYTE
0, defines the device indentifier, 0101 in the upper half;
and the device slave address in the low half of the byte.
The slave address is determined by the logic values of
the A0, A1, and A2 pins of the X9470. This allows for
up to 8 unique addresses for the X9470. The next byte,
Start Condition
All commands are preceded by the start condition,
which is a HIGH to LOW transition of SDA when SCL is
HIGH. The device continuously monitors the SDA and
SCL lines for the start condition and will not respond to
any command until this condition has been met. See
Figure 9.
