NOTES:
1. B1 Represents Bank #1; B2 Represents Bank #2. Each Bank consists of one IDT709279/69 for this waveform, and are setup for depth expansion in this
example. ADDRESS(B1) = ADDRESS(B2) in this situation.
2. UB, LB, OE, and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH.
3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
4. CE0, UB, LB, and ADS = VIL; CE1, CNTEN, and CNTRST = VIH.
5. OE = VIL for the Right Port, which is being read from. OE = VIH for the Left Port, which is being written to.
6. If tCCS < maximum specified, then data from right port READ is not valid until the maximum specified for tCWDD.
If tCCS > maximum specified, then data from right port READ is not valid until tCCS + tCD1. tCWDD does not apply in this case.
