1. CLK must be LOW during asynchronous read and asynchronous write modes and to achieve
2. The WAIT polarity is configured through the bus configuration register (BCR[10]).
3. When LB# and UB# are in select mode (LOW), DQ[15:0] are enabled. When only LB# is in
standby power during standby and DPD modes. CLK must be static (HIGH or LOW) during
burst suspend.
select mode, DQ[7:0] are enabled. When only UB# is in the select mode, DQ[15:8] are
enabled.
