Notes:
1. The device can be in only one state at a time. Depending on the state of the device,
some operations are allowed (Yes) and others are not (No). For example, when the de-
vice is in the standby state, all operations except SUSPEND are allowed in any sector. For
all device states except the erase suspend state, if an operation is allowed or disallowed
in one sector, it is allowed or disallowed in all other sectors. In the erase suspend state, a
PROGRAM operation is allowed in any sector except the one in which an ERASE opera-
tion has been suspended.
2. All READ operations except READ STATUS REGISTER and READ FLAG REGISTER. When is-
sued to a sector or subsector that is simultaneously in an erase suspend state, the READ
operation is accepted, but the data output is not guaranteed until the erase has comple-
ted.
3. All PROGRAM operations except PROGRAM OTP. In the erase suspend state, a PROGRAM
operation is allowed in any sector (Yes) except the sector (No) in which an ERASE opera-
tion has been suspended.
4. Applies to the SECTOR ERASE or SUBSECTOR ERASE operation.
5. Applies to the following operations: WRITE STATUS REGISTER, WRITE NONVOLATILE
CONFIGURATION REGISTER, PROGRAM OTP, and BULK ERASE.
6. Applies to the following operations: WRITE ENABLE, WRITE DISABLE, CLEAR FLAG STA-
TUS REGISTER, WRITE LOCK REGISTER, WRITE VOLATILE, and ENHANCED VOLATILE CON-
FIGURATION REGISTER.
7. Applies to the READ STATUS REGISTER or READ FLAG STATUS REGISTER operation.
8. Applies to the PROGRAM SUSPEND or ERASE SUSPEND operation.
PROGRAM/ERASE RESUME Command
To initiate the PROGRAM/ERASE RESUME command, S# is driven LOW. The command
code is input on DQ0. The operation is terminated by driving S# HIGH.
When this command is executed, the status register write in progress bit is set to 1, and
the flag status register program erase controller bit is set to 0. This command is ignored
if the device is not in a suspended state.
