I2S input data format
The TDA7803A accepts I2S standard interface format as in Figure 39 and the I2C bit
configuration is IB3 [D5,D4,D3] = "000".

TDM input data format
TDM 4-channel is allowed for TDA7803A and it is as in Figure 40. All the channels are sent
on the audio data line SD24. The channel's order is 1, 2, 3 and 4. The I2C bit configuration is
IB3 [D5, D4, D3] = "001".
Figure 40. TDM 16 (8+8) - channel format
TDM 8-channel is also allowed and two devices (device 1 and device 2) can be driven by
using just one serial data line SD24. There are two selectable options.
When IB3 [D5,D4,D3] = "010" device 1 is first sent; when IB3 [D5,D4,D3] = "011" device 2 is
first sent. In Figure 41 TDM 8-channel format is showed.
