DAC OUTPUT CONTROL
The DAC output control word determines how the left and right inputs to the audio Interface are
applied to the left and right DACs:

DAC DIGITAL AUDIO INTERFACE CONTROL REGISTER
Interface format is selected via the FMT[1:0] register bits:

Interface Control
BIT

LABEL
FMT

DEFAULT
00
DESCRIPTION
Interface format Select
00 : right justified mode
01: left justified mode
10: I
2
S mode
11: DSP Modes A or B
In left justified, right justified or I
2
S modes, the LRP register bit controls the polarity of LRCLK. If this
bit is set high, the expected polarity of LRCLK will be the opposite of that shown Figure 13, Figure 14
and Figure 15. Note that if this feature is used as a means of swapping the left and right channels, a
1 sample phase difference will be introduced. In DSP modes, the LRP register bit is used to select
between modes A and B.
