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