State
The table reflects behavior if R-UB# and R-LB# are asserted low. If only either of the signals, R-UB# or R-LB# is
asserted low only the corresponding data byte will be written (UB# enables DQ15-DQ8, LB# enables DQ7-DQ0).
During a write access invoked by R-WE# set to low the R-OE# signal is ignored.
Power mode of Standby or Active will depend on the internal operation of device at the time.
Clock configuration is rising edge.
Output drivers are controlled by the asynchronous R-OE# control signal.
During the initial command cycle R-OE# is don’t care (X) and subsequent cycles it must be low (L)
