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