RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of re-
setting the device to reading array data. When the
system drives the RESET# pin to V
riod of t
operation in progress, tristates all data output pins,
and ignores all read/write attempts for the duration of
the RESET# pulse. The device also resets the internal
state machine to reading array data. The operation
that was interrupted should be reinitiated once the de-
vice is ready to accept another command sequence,
to ensure data integrity.
Current is reduced for the duration of the RESET#
pulse. When RESET# is held at V
draws CMOS standby current (I

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 deter mine
whether the reset operation is complete. If RESET#
is asserted when a program or erase operation is not
executing (RY/BY# pin is “1”), the reset operation is
completed within a time of t
