CKS
CKI affects only the Transmit Clock and not the output clock signal.
1: The data outputs (Data and Frame Sync signals) are shifted out on transmit clock rising edge. The Frame sync signal input is
sampled on transmit clock falling edge.
0: The data outputs (Data and Frame Sync signals) are shifted out on transmit clock falling edge. The Frame sync signal input is
sampled on transmit clock rising edge.
