Mode
For asynchronous read operation, all die may be simultaneously selected, but may not simultaneously drive the memory
bus. For synchronous burst-mode reads, only two die (one flash and the PSRAM) may be simultaneously selected.
WAIT is only valid during synchronous flash reads. WAIT is driven if F-CE# is asserted.
F1-CE# for Flash Die#1, F2-CE# for Flash Die#2. F1-OE# is for Flash Die#1, F2-OE# for Flash Die#2.
For either flash die, F[2:1]-OE# and F-WE# should never be asserted simultaneously. If done so on a particular flash
die, F[2:1]-OE# will override F-WE#.
For PSRAM, R-OE# and R-WE# should never be asserted simultaneously.
X can be V
Flash CFI query and status register accesses use D[7:0] only, all other reads use D[15:0].
Refer to W30/W18 datasheet for Valid D
