NOTES:
1. x9 to x9 mode: X = 17 for the IDT72V2103 and X = 18 for the IDT72V2113.
2. All other modes: X = 16 for the IDT72V2103 and X = 17 for the IDT72V2113.
NOTES:
1. If the part is empty at the point of Retransmit, the output ready flag (OR), will be updated based on RCLK (Retransmit clock cycle), valid data will also appear on the output.
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 procedure.
3. OE = LOW
4. W
5. There must be at least two words written to the FIFO before a Retransmit operation can be invoked.
6. RM is set LOW during MRS.
