NOTES:
1. ZZ input is LOW, GW is HIGH and LBO is Don't Care for this cycle.
2. O4 (Aw) represents the final output data in the burst sequence of the base address Aw. I1 (Ax) represents the first input from the external address Ax. I1 (Ay) represents the first input
from the external address Ay; I2 (Ay) represents the next input data in the burst sequence of the base address Ay, etc. where A0 and A1 are advancing for the four word burst in the
sequence defined by the state of the LBO input. In the case of input I2 (Ay) this data is valid for two cycles because ADV is high and has suspended the burst.
3. CS
0 timing transitions are identical but inverted to the CE and CS1 signals. For example, when CE and CS1 are LOW on this waveform, CS0 is HIGH.

NOTES:
1. Device must power up in deselected Mode
2. LBO is Don't Care for this cycle.
3. It is not necessary to retain the state of the input registers throughout the Power-down cycle.
4. CS
0 timing transitions are identical but inverted to the CE and CS1 signals. For example, when CE and CS1 are LOW on this waveform, CS0 is HIGH.

NOTES:
1. ZZ input is LOW, ADV is HIGH and LBO is Don't Care for this cycle.
2. (Ax) represents the data for address Ax, etc.
3. For read cycles, ADSP and ADSC function 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.
