7.1
The UDA1355H can be controlled either via static pins or
via the microcontroller serial hardware interface being the
I
clock up to 2 MHz. It is recommended to use the
microcontroller interface since this gives full access to all
the IC features.
The two microcontroller interfaces only differ in interface
format. The register addresses and features that can be
controlled are identical for L3-bus mode and I
mode.
The UDA1355H can operate in three control modes:
• Static mode with limited features
• L3-bus mode with full featuring
• I
The modes are selected via the 3-level pin SEL_STATIC
according to Table 2.

7.2
The UDA1355H has a microcontroller interface and all the
sound processing features and system settings can be
controlled by the microcontroller.
The controllable settings are:
• Restoring L3-bus defaults
• Power-on settings for all blocks
• Digital interface input and output formats
• Volume settings for the decimator
• PGA gain settings
