trol signals. Standard address access timings provide new data when addresses
are changed. While in sleep mode, output data is latched and always available to
automatic sleep mode current specification.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of resetting the device to reading
array data. When the RESET# pin is driven low for at least a period of tRP, the
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 op-
eration 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 VSS±0.3 V, the device draws CMOS standby current (ICC5). If RESET# is held
at VIL but not within VSS±0.3 V, the standby current will be greater.
The RESET# pin may be tied to the system reset circuitry. A system reset would
thus also reset the Flash memory, enabling the system to read the boot-up firm-
ware from the Flash memory.
Refer to the AC Characteristics tables for RESET# parameters and to
Figure 13for the timing diagram.
Output Disable Mode
When the OE# input is at VIH, output from the device is disabled. The output pins
are placed in the high impedance state.
