COMMUNICATION PROTOCOL
IIC Communication Protocol
This is a two-wire serial communication link that is fully com-
patible with the IIC bus system. It consists of SDA bidirectional
data line and SCL clock input line. Data is sent from a transmitter
(master), to a receiver (slave) via the SDA line, and is synchro-
nized with a transmitter clock on the SCL line at the receiving
end. The maximum data rate is limited to 400kbps. The default
chip address is $70. Please refer to the IIC-Bus specification for
the detail timing requirement.
Operating Procedure
FIGURE 7. shows the IIC transmission format. The master ini-
tiates a transmission routine by generating a START condition,
followed by a slave address byte. Once the address is properly
identified, the slave will respond with an ACKNOWLEDGE signal
by pulling the SDA line LOW during the ninth SCL clock. Each
data byte which then follows must be eight bits long, plus the
ACKNOWLEDGE bit, to make up nine bits together. Appropriate
hub setting information can be downloaded sequentially. See
Data Transmission Format for details. In the cases of no AC-
KNOWLEDGE or completion of data transfer, the master will
generate a STOP condition to terminate the transmission rou-
tine.

DATA TRANSMISSION FORMAT
After the proper identification by the receiving device, Mas-
ter is now ready to program MC141556 by transmitting the
configuration data. The configuration data is shown in Table2
Programmable Configuration Data. To complete the program-
ming sequence, all six bytes of data are needed to be trans-
mitted. The transmission sequence is defined in Table2 . An
ACKNOWLEDGE bit must be inserted between each byte of
data as shown in FIGURE 8.
