SECTOR ERASE SUSPEND

During sector erasure, sector erase suspend is the only valid command. If user issue erase suspend command

in the time-out period of sector erasure, device time-out period will be over immediately and the device will go

back to erase-suspended read array mode. If user issue erase suspend command during the sector erase is be-

ing operated, device will suspend the ongoing erase operation, and after the Tready1(<=20us) suspend finishes

and the device will enter erase-suspended read array mode. User can judge if the device has finished erase sus-

pend through Q6, Q7, and RY/BY#.

After device has entered erase-suspended read array mode, user can read other sectors not at erase suspend

by the speed of Taa; while reading the sector in erase-suspend mode, device will output its status. User can use

Q6 and Q2 to judge the sector is erasing or the erase is suspended.

When the device has suspended erasing, user can execute the command sets except sector erase and chip

erase, such as read silicon ID, sector protect verify, program, and erase resume.

SECTOR ERASE RESUME

Sector erase resume command is valid only when the device is in erase suspend state. After erase resume, user

can issue another erase suspend command, but there should be a 400us interval between erase resume and

the next erase suspend. If user issue infinite suspend-resume loop, or suspend-resume exceeds 1024 times, the

time for erasing will increase.
