CKI affects only the receive clock and not the output clock signal.
1: The data inputs (Data and Frame Sync signals) are sampled on receive clock rising edge. The Frame Sync signal output is
shifted out on receive clock falling edge.
0: The data inputs (Data and Frame Sync signals) are sampled on receive clock falling edge. The Frame Sync signal output is
shifted out on receive clock rising edge.
