NOTE:
1. X = 17 for the IDT72V2101 and X = 18 for the IDT72V2111.
NOTES:
1. Retransmit setup is complete after OR returns LOW.
2. No more than D - 2 words may be written to the FIFO between Reset (Master or Partial) and Retransmit setup. Therefore, IR will be LOW throughout the Retransmit setup
3. OE = LOW
4. W
5. There must be at least two words written to the FIFO before a Retransmit operation can be invoked.
