8.14 Microcontroller interface mode
9.1 General
The microcontroller interface mode can be selected as shown in
Table 11:
Table 12:
All the features are accessible with the I
interface protocol.
The detailed description of the device operation in the L3-bus mode and I
given in
The UDA1384 has an L3-bus microcontroller interface and all the digital sound processing
features and various system settings can be controlled by a microcontroller.
The exchange of data and control information between the microcontroller and the
UDA1384 is LSB first and is accomplished through a serial hardware L3-bus interface
comprising the following pins:
The L3-bus format has two modes of operation:
The address mode is used to select a device for a subsequent data transfer. The address
mode is characterized by signal L3MODE = LOW and a burst of 8 pulses for signal
L3CLOCK, accompanied by 8 bits (see
