Solutions for a Real Time World
Digital Audio Interface (I²S)
The digital audio interface supports the industry standard formats for I²S, left-justified (LJ) or
right-justified (RJ). The interface shares the same pins as the PCM interface, which means each
audio bus is mutually exclusive in its usage. Table 7 lists these alternative functions.
Table 8 describes the values for the PS Key (PSKEY_DIGITAL_AUDIO_CONFIG) that is used to
set-up the digital audio interface. For example, to configure an I²S interface with 16-bit SD data
set PSKEY_DIGITAL_CONFIG to
0x0406.

Description
0 for left justified, 1 for right
justified.
For left justified formats: 0 is MSB of
SD data occurs in the first SCLK
period following WS transition. 1 is
MSB of SD data occurs in the second
SCLK period.
For 0, SD data is left channel when
WS is high. For 1 SD data is right
channel.
For 0, 17 bit SD data is rounded
down to 16 bits. For 1, the audio
attenuation defined in
CONFIG_AUDIO_ATTEN is applied
over 24 bits with saturated rounding.
Requires CONFIG_16_BIT_CROP_EN
to be 0.
Attenuation in 6 dB steps.
