NOTE: P symbolizes clock pulse
1. When UB# and LB# are in select mode (LOW), I/O0-I/O15 are affected as shown. When only LB# is in select mode, I/O0-I/O7 are
affected as shown. When only UB# is in the select mode, I/O8-I/O15 are affected as shown.
2. When the device is in standby mode, address inputs and data inputs/outputs are internally isolated from any external influence.
3. Burst Mode operation is initialized through the Bus Configuration Register (BCR[15]).
4. The device will consume active power in this mode whenever addresses are changed.
5. The WAIT polarity is configured through the Bus Configuration Register (BCR[10]).
6. VIN = VCCQ or 0V, all device pins must be static (unswitched) in order to achieve standby current.
7. The clock polarity is configured through the Bus Configuration Register (BCR[6]).
8. P refers to a clock pulse.
9. DPD is maintained until the Refresh Configuration Register is reconfigured.
