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.
Selected Receive Clock
Divided clock
TX_CLOCK clock signal
RX_CLOCK pin
Reserved
Continuous, as soon as the receiver is enabled, and immediately after the end of
transfer of the previous data.
