Figure 15. Serial Loading of Programmable Flag Registers (IDT Standard and FWFT Modes)
NOTE:
1. X = 9 for the IDT72V3640, X = 10 for the IDT72V3650, X = 11 for the IDT72V3660, X = 12 for the IDT72V3670, X = 13 for the IDT72V3680 and X = 14 for the IDT72V3690.
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.
D = 1,025 for the IDT72V3640, 2,049 for the IDT72V3650, 4,097 for the IDT72V3660, 8,193 for the IDT72V3670, 16,385 for the IDT72V3680 and 32,769 for the IDT72V3690.
3.
OE = LOW.
4. W1, W2, W3 = first, second and third words written to the FIFO after Master Reset.
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.
