assumed to be valid. OE#-low activates the outputs and gates selected data onto the I/
O bus. WE#-low enables device write operations. When the VPP voltage
(lockout voltage), only read operations are enabled.
Reads
To perform a read operation, RST# and WE# must be deasserted while CE# and OE#
are asserted. CE# is the device-select control. When asserted, it enables the flash
memory device. OE# is the data-output control. When asserted, the addressed flash
memory data is driven onto the I/O bus.
Writes
To perform a write operation, both CE# and WE# are asserted while RST# and OE# are
deasserted. During a write operation, address and data are latched on the rising edge
of WE# or CE#, whichever occurs first.

command. See
Output Disable
When OE# is deasserted, device outputs DQ[15:0] are disabled and placed in a high-
impedance (High-Z) state, WAIT is also placed in High-Z.
Standby
When CE# is deasserted the device is deselected and placed in standby, substantially
reducing power consumption. In standby, the data outputs are placed in High-Z,
independent of the level placed on OE#. Standby current, I
measured over any 5 ms time interval, 5 μs after CE# is deasserted. During standby,
average current is measured over the same time interval 5 μs after CE# is deasserted.
