For flash, do not simultaneously assert F-OE# and F-WE#. For PSRAM, do not simultaneously assert
R-OE# and R-WE#.

Flash CFI query and Status Register accesses, use DQ[7:0] only. All other reads use DQ[15:0].
P-CRE# is low if PSRAM is in standby. P-CRE# is X if PSRAM is in Low-Power mode. See
Operations” on page 37
WAIT indicates data validity only when in Synchronous mode. Ignore this setting in Asynchronous and Page-mode.
The Flash and Synchronous PSRAM dies share the WAIT signal.
During AD-Mux I/O operation, ADV# must remain deasserted during the data phase.

Flash and PSRAM Device Bus Operations
Device Operation Overview
The following sections describes the bus operations and device state between the flash
and synchronous PSRAM.
Flash and Synchronous PSRAM Bus Operations
Bus operations for the W18 stacked device involve the control of flash and PRAM inputs.
The bus operations are shown in
See the Intel
Mux I/O doc #290701 and ADMux I/O doc #313272) for complete descriptions of the
flash modes and commands, command bus-cycle definitions, and flowcharts that
