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.
When the device is deselected (while CE# is deasserted) during a program or erase
operation, it continues to consume active power until the program or erase operation is
completed.
Reset
As with any automated device, it is important to assert RST# when the system is reset.
When the system comes out of reset, the system processor attempts to read from the
flash memory if it is the system boot device. If a CPU reset occurs with no flash
memory reset, improper CPU initialization may occur because the flash memory may
be providing status information rather than array data. Flash memory devices from
Numonyx allow proper CPU initialization following a system reset through the use of the
RST# input.
After initial power-up or reset, the device defaults to asynchronous Read Array mode,
and the Status Register is set to 0x80.
When RST# is driven low (RST# asserted), the flash device enters reset mode. Then all
internal circuits are de-energized, and the output drivers are placed in High-Z. If RST#
is asserted during a program or erase operation, the operation is terminated and the
memory contents at the aborted location (for a program) or block (for an erase) are no
longer valid. A device reset also clears the Status Register. See
Reset” on page 46
When RST# is driven high (RST# deasserted), a minimum wait is required before the
flash device is able to perform normal operations. Please consider t
