Figure 31 shows the default I2S-justified mode. The frame sync

is low for the left channel and HI for the right channel. Data is

valid on the rising edge of serial clock. The MSB is left-justified

to the frame sync transition but with a delay.

Figure 32 shows the left-justified mode. The frame sync is high

for the left channel and low for the right channel. Data is valid

on the rising edge of serial clock. The MSB is left-justified to the

frame sync transition with no delay.
