Besides the L3-bus mode the UDA1342TS supports the
I
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
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
in Fig.15.
8.16.1
Before any data is transmitted on the I
which should respond is addressed first. The addressing is
always done with the first byte transmitted after the START
procedure (S).
8.16.2
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.
Table 15 I
The slave address bit IPSEL corresponds to the hardware
address pin IPSEL which allows selecting the slave
address.
