The sound processing and other feature values are stored
in independent registers.
The first selection of the registers is achieved by the choice
of data type that is transferred. This is performed in the
address mode using bit 0 and bit 1 (see Table 4).
The second selection is performed by the 2 or 3 MSBs of
the data byte (bits 7 and 6 or bits 7, 6 and 5).
The other bits in the data byte (bits 5 to 0 or bits 4 to 0)
represent the value that is placed in the selected registers.
For the UDA1341TS the following modes can be selected:

There are two addressing modes: direct addressing
mode and extended addressing mode.
Direct addressing mode is using the 2 MSB bits of the
data byte. Via this addressing mode the features
volume, bass boost, treble, peak position, de-emphasis,
mute, and mode can be controlled directly.
Extended addressing mode is provided for controlling
the features digital mixer, AGC control, MIC sensitivity,
input gain, AGC time constants, and AGC output level.
An extended address can be set via the EA registers
(3 bits). The data in the extended registers can be set by
writing data to the ED registers (5 bits).
In this mode the detected peak level value can be read
out.
