RESET#: Hardware Reset Pin
Output Disable Mode
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 t
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 operation 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 V
draws CMOS standby current (I
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 firmware from the Flash memory.
If RESET# is asserted during a program or erase operation, 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 executing (RY/BY# pin is 1), the reset operation is
completed within a time of t
RESET# pin returns to V
