RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of re-
setting the device to reading array data. When the RE-
SET# pin is driven low for at least a period of t
device immediately terminates any operation in
progress, tristates all output pins, and ignores all
read/write commands for the duration of the RESET#
pulse. The device also resets the internal state ma-
chine to reading array data. The operation that was in-
terrupted should be reinitiated once the device is
ready to accept another command sequence, to en-
sure data integrity.
Current is reduced for the duration of the RESET#
pulse. When RESET# is held at V

The RESET# pin may be tied to the system reset cir-
cuitry. A system reset would thus also reset the Flash

ware from the Flash memory.
If RESET# is asserted during a program or erase op-
eration, the RY/BY# pin remains a “0” (busy) until the
internal reset operation is complete, which requires a
time of t
system can thus monitor RY/BY# to determine
whether the reset operation is complete. If RESET# is
asserted when a program or erase operation is not ex-
ecuting (RY/BY# pin is “1”), the reset operation is com-
pleted within a time of t
