PRINCIPLES OF OPERATION  
The X9409 is highly integrated microcircuit  
incorporating four resistor arrays and their associated  
registers and counters and the serial interface logic  
providing direct communication between the host and  
the XDCP potentiometers.  
Stop Condition  
All communications must be terminated by a stop  
condition, which is a LOW to HIGH transition of SDA  
while SCL is HIGH.  
a
Acknowledge  
Acknowledge is a software convention used to provide  
a positive handshake between the master and slave  
devices on the bus to indicate the successful receipt of  
data. The transmitting device, either the master or the  
slave, will release the SDA bus after transmitting eight  
bits. The master generates a ninth clock cycle and  
during this period the receiver pulls the SDA line LOW  
to acknowledge that it successfully received the eight  
bits of data.  
Serial Interface  
The X9409 supports a bidirectional bus oriented  
protocol. The protocol defines any device that sends  
data onto the bus as a transmitter and the receiving  
device as the receiver. The device controlling the  
transfer is a master and the device being controlled is  
the slave. The master will always initiate data transfers  
and provide the clock for both transmit and receive  
operations. Therefore, the X9409 will be considered a  
slave device in all applications.  
The X9409 will respond with an acknowledge after  
recognition of a start condition and its slave address  
and once again after successful receipt of the  
command byte. If the command is followed by a data  
byte the X9409 will respond with a final acknowledge.  
Clock and Data Conventions  
Data states on the SDA line can change only during  
SCL LOW periods (t  
). SDA state changes during  
LOW  
SCL HIGH are reserved for indicating start and stop  
conditions.  
Array Description  
The X9409 is comprised of four resistor arrays. Each  
array contains 63 discrete resistive segments that are  
connected in series. The physical ends of each array  
are equivalent to the fixed terminals of a mechanical
