This is the recovery for input phase jumps.
The receiver latency as shown in Figure 6, is defi ned as the time between receiving the fi rst serial bit of a parallel data word (defi ned as the
fi rst edge of the fi rst serial bit) and the clocking out of that parallel word (defi ned by the rising edge of the receive byte clock, either RBC1 or
RBC0).
