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

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 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
