8.2
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 17 lists these alternative functions. Figure 26
shows the timing diagram.
Table 17: Alternative Functions of the Digital Audio Bus Interface on the PCM Interface.
Table 18 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.
