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 th us mo nito r RY /BY# to de termin e
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.
