32. Read from Last Physical Location.
33. Clocks are free running in this case.
34. The flags may change state during Retransmit as a result of the offset of the read and write pointers, but flags will be valid at t
35. For the synchronous PAE and PAF flags (SMODE), an appropriate clock cycle is necessary after t
