STV82x7

I²S Interface (In / Out)

Note: 1 The I²S input and output modes are exclusive (this means that the I2S_DATA0 can be used as input

or as output).

2 Simultaneous processing of I²S inputs and SIF inputs and/or ADC inputs (SCART or MONO inputs)

is NOT possible with the device.

3 I2S_PCM_CLK is not needed for the device.

Both standard and non-standard modes are available, see Figure 29.
