• CKI: Receive Clock Inversion
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.
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.
CKI affects only the Receive Clock and not the output clock signal.
