SERIAL AUDIO INTERFACE DATA FORMATS IN ENCODING MODE
In encoding mode, the serial audio data input for the PASC processor is taken from the SD1 pin. This data is scaled by
the fade processor before being sent to the PASC processor. The output from the fade processor is sent in parallel to
the SD2 output.
Both I2S and EIAJ formats are supported.

Note
1. If SD1 is used in EIAJ mode, and the data from SD2 is required, the IECOP can be re-programmed to provide a
suitable I2S WS signal for SD2. The IEC 958 output is not available in this mode.
SERIAL AUDIO INTERFACE DATA FORMATS IN DECODING MODE
In decoding mode, the output from the PASC processor, connected via the fade processor, is present at both SD1 and
SD2.
Both I2S and EIAJ formats are supported.

Note
1. The sub-band filter performs rounding to 16 or 18 bits according to the operating mode of the interface.
SERIAL AUDIO INTERFACE MODE CONTROL
The operating mode of the interface is programmed by the extended settings registers as shown in Table 6.
