SLAS553A – NOVEMBER 2008 – REVISED SEPTEMBER 2009...................................................................................................................................... www.ti.com
When time-based-slot mode is enabled with no channel swapping, the MSB of the left channel is valid on the
(Offset1 + 1)th rising edge of the bit clock following the rising edge of the word clock. And, the MSB of the right
channel is valid on the (Ch_Offset_2 + 1)th rising edge of the bit clock following the LSB of the left channel.
Figure 21 shows the operation with time-based-slot mode enabled and Ch_Offset_1 = 0 and Ch_Offset_2 = 1.
The MSB of the left channel is valid on the first rising edge of the bit clock after the rising edge of the word clock.
Data transfer for the right channel does not wait for the falling edge of the word clock, and the MSB of the right
channel is valid on the second rising edge of the bit clock after the LSB of the left channel.
Figure 21. Left-Justified Mode, Time-Based-Slot Mode Enabled, Ch_Offset_1 = 0, Ch_Offset_2 = 1
For the case with time-based-slot mode enabled and channel swapping enabled, the MSB of the right channel is
valid on the (Ch_Offset_1 + 1)th rising edge of the bit clock following the rising edge of the word clock. And, the
MSB of the left channel is valid on the (Ch_Offset_2 + 1)th rising edge of the bit clock following the LSB of the
right channel. Figure 22 shows the operation in this mode with Ch_Offset_1 = 0 and Ch_Offset_2 = 1. The MSB
of the right channel is valid on the first rising edge of the bit clock after the rising edge of the word clock. Data
transfer for the left channel starts following the completion of data transfer for the right channel without waiting for
the falling edge of the word clock. The MSB of the left channel is valid on the second rising edge of the bit clock
after the LSB of the right channel.
Figure 22. Left-Justified Mode, Time-Based-Slot Mode Enabled, Ch_Offset_1 = 0, Ch_Offset_2 = 1,
Channel Swapping Enabled
In I2S mode, the MSB of the left channel is valid on the second rising edge of the bit clock after the falling edge
of the word clock. Similarly, the MSB of the right channel is valid on the second rising edge of the bit clock after
