INTRODUCTION
The exchange of data and control information between the
microcontroller and the UDA1342TS is accomplished
through a serial hardware interface comprising the
following pins:
L3DATA: microcontroller interface data line
L3MODE: microcontroller interface mode line
L3CLOCK: microcontroller interface clock line.
The UDA1342TS acts as a slave receiver or a slave
transmitter. Therefore L3CLOCK and L3MODE lines
transfer only input data and the L3DATA line transfers
bidirectional data.
