Q
NOTES:
1. Retransmit setup is complete after EF returns HIGH, only then can a read operation begin.
2. OE = LOW.
3. W
4. No more than D - 2 may be written to the FIFO between Reset (Master or Partial) and Retransmit setup. Therefore, FF will be HIGH throughout the Retransmit setup procedure.
5. There must be at least two words written to and two words read from the FIFO before a Retransmit operation can be invoked.
6. RM is set HIGH during MRS.
