1. To ensure that the earlier of the two ports wins. t APS is ignored for M/ S = V IL (SLAVE).
2. CE L = CE R = V IL
3. OE = V IL for the reading port.
4. If M/ S = V IL (SLAVE), then BUSY is an input ( BUSY "A" = V IH and BUSY "B" = "don't care", for this example).
5. 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. t WH must be met for both BUSY input (SLAVE) and output (MASTER).
2. BUSY is asserted on port "B" blocking R/ W "B" , until BUSY "B" goes HIGH.
