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
READY
(during Embedded Algorithms). The
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
READY
(not during Embedded
Algorithms). The system can read data t
RH
after the
RESET# pin returns to V
IH
.
Refer to the AC Characteristics tables for RESET# pa-
rameters and to Figure 14 for the timing diagram.
Output Disable Mode
When the OE# input is at V
IH
, output from the device is
disabled. The output pins are placed in the high
impedance state.
