mode. The system can determine the status of the

program operation using the DQ7 or DQ6 status bits,

just as in the standard word program operation.

Refer to the Write Operation Status section for more

information.

In the erase-suspend-read mode, the system can also

issue the autoselect command sequence. Refer to the

Autoselect Mode and Autoselect Command Sequence

sections for details.

To resume the sector erase operation, the system

must write the Erase Resume command. The address

of the erase-suspended sector is required when writ-

ing this command. Further writes of the Resume com-

mand are ignored. Another Erase Suspend command

can be written after the chip has resumed erasing.
