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 procedure.
3. OE = LOW.
4. W
5. OR goes LOW at 60 ns + 2 RCLK cycles + t
NOTE:
1. X = 13 for the IDT72V261LA and X = 14 for the IDT72V271LA.
