Non-Burst Read Cycle Timing Waveform

NOTES:

1. ZZ input is LOW,ADV is HIGH andLBO is Don't Care for this cycle.

2. (Ax) represents the data for address Ax, etc.

3. For read cycles,ADSP andADSCfunction identically and are therefore interchangable.

NOTES:

1. ZZ input is LOW, ADV and OE are HIGH, and LBO is Don't Care for this cycle.

2. (Ax) represents the data for address Ax, etc.

3. Although only GW writes are shown, the functionality of BWE and BWx together is the same as GW.

4. For write cycles, ADSP and ADSC have different limitations.
