Timing Waveform of Write with Port-to-Port Read and BUSY(1,2,3)

tWC

ADDR"A"

tWP

R/W"A"

tWDD

DATAOUT "B"

tDDD(4)

NOTES:

1. To ensure that the earlier of the two ports wins, tAPS is ignored for Slave (IDT7143).

2. CEL = CER = VIL

3. OE = VIL for the reading port.

4. All timing is the same for left and right ports. Port "A" may be either the left or right port. Port "B" is the port opposite from port "A".

NOTES:

1. tWH must be met for both BUSY input (IDT7143, slave) and output (IDT7133, master).

2. BUSY is asserted on port "B" blocking R/W"B", until BUSY"B" goes HIGH.

3. All timing is the same for left and right ports. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
