information.

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

issue the autoselect command sequence. Refer to the

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.
