LJF is a dual-phase format with a 50% WCLK duty cycle and the start of an MSB of each sample word aligned with each edge of WCLK. For any given frame, the left channel is transferred first when WCLK is high, and the right channel is transferred next when WCLK is low.
Data is sampled on the rising edge of BCLK and updated on the falling edge of BCLK. Figure 25-3 shows the LJF serial format.
