Figure 23. I2S Mode (Standard Timing)
Figure 24 shows the I2S mode timing with Ch_Offset_1 = 2.
Figure 24. I2S Mode With Ch_Offset_1 = 2
Figure 25 shows the I2S mode timing with Ch_Offset_1 = 0 and bit clock inverted.
Figure 25. I2S Mode With Ch_Offset_1 = 0, Bit Clock Inverted
For I2S mode, the number of bit clocks per channel should be greater than or equal to the programmed word
length of the data. Also the programmed offset value should be less than the number of bit clocks per frame by
at least the programmed word length of the data.
In DSP mode, the rising edge of the word clock starts the data transfer with the left-channel data first and is
immediately followed by the right-channel data. Each data bit is valid on the falling edge of the bit clock.
Figure 26 shows the standard timing for the DSP mode.
