RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of reset-
ting the device to reading array data. When the
RESET# 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 machine to
reading array data. The operation that was interrupted
should be reinitiated once the device 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

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

If RESET# is asserted during a program or erase oper-
ation, 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 executing
(RY/BY# pin is “1”), the reset operation is completed
within a time of t
rithms). The system can read data t
