NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
2. CE 0 , UB , LB , and ADS = V IL ; CE 1 , CNTEN , and CNTRST = V IH .
3. OE = V IL for the Right Port, which is being read from. OE = V IH for the Left Port, which is being written to.
4. If t CCS < maximum specified, then data from right port READ is not valid until the maximum specified for t CWDD .
If t CCS > maximum specified, then data from right port READ is not valid until t CCS + t CD1 . t CWDD does not apply in this case.
5. All timing is the same for both left and right ports. Port "A" may be either left or right port. Port "B" is the opposite of Port "A".

1. CE 0 , BE n , and ADS = V IL ; CE 1 , CNTEN , and REPEAT = V IH .
2. OE = V IL for Port "B", which is being read from. OE = V IH for Port "A", which is being written to.
3. If t CO < minimum specified, then data from Port "B" read is not valid until following Port "B" clock cycle (ie, time from write to valid read on opposite port will be
t CO + 2 t CYC2 + t CD2 ). If t CO > minimum, then data from Port "B" read is available on first Port "B" clock cycle (ie, time from write to valid read on opposite port
will be t CO + t CYC2 + t CD2 ).
4. All timing is the same for Left and Right ports. Port "A" may be either Left or Right port. Port "B" is the opposite of Port "A"
