3.1 General
The chip provides an IIC (SCL3/SDA3) serial bus interface to communicate with the host. The IIC address
for this slave IIC interface is “0111_0_A1_0_x” (where x=1 for read and x=0 for write). A1 is
programmable by pin.
3.2 IIC Interface
The IIC bus interface uses a Serial Data line (SDA at pin SDA3) and a Serial Clock Line (SCL at pin SCL3)
for data transfer. The chip acts as a slave for receiving and transmitting data over the serial interface. All
devices connected to the IIC bus must have open drain or open collector outputs. Logic AND function is
exercised on both lines with external pull-up resistors, the value of these resistors is system dependent.
When the serial interface is not active, the logic levels on SCL and SDA are pulled HIGH by external
pull-up resistors.
Data received or transmitted on the SDA line must be stable at the positive edge of SCL. If the SDA changes
state while SCL is HIGH, the IIC interface interprets that action as a START or STOP sequence. Data on
SDA must change only when SCL is LOW.
The standard IIC traffic protocol is illustrated in the following Figure:
