The RESET# pin may be tied to the system reset cir-
cuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firm-
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-
