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 oper-

ation, the RY/BY# pin remains a “0” (busy) until the

internal reset operation is complete, which requires a

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

Refer to

AC Characteristics, on page 26 for RESET#

parameters and to Figure 14, on page 27 for the timing

diagram.
