I

C-bus interface
Besides the L3-bus mode the UDA1342TS supports the
I
2
C-bus mode; all the features can be controlled by the
microcontroller with the same register addresses as used
in the L3-bus mode.
The exchange of data and control information between the
microcontroller and the UDA1342TS in the I
2
C-bus mode
is accomplished through a serial hardware interface
comprising the following pins and signals:
L3CLOCK: Serial Clock Line (SCL)
L3DATA: Serial Data line (SDA).
The clock and data timing of the I
2
C-bus transfer is shown
in Fig.15.

LAVE ADDRESS
The UDA1342TS acts as a slave receiver or a slave
transmitter. Therefore, the clock signal SCL is only an
input signal. The data signal SDA is an input or output
signal (bidirectional line).
The UDA1342TS slave address format is shown in
Table 15.

C-bus slave address format
The slave address bit IPSEL corresponds to the hardware
address pin IPSEL which allows selecting the slave
address.

The UDA1342TS register address format is given in
Table 16.
