Data Sheet
The system may also write the autoselect command sequence when the device is in the Erase Suspend
mode. The device allows reading autoselect codes even at addresses within erasing sectors, since the codes
are not stored in the memory array. When the device exits the autoselect mode, the device reverts to the
Erase Suspend mode, and is ready for another valid operation. See Autoselect Command Sequence
on page 25 for more information.
The system must write the Erase Resume command (address bits are don’t care) to exit the erase suspend
mode and continue the sector erase operation. Further writes of the Resume command are ignored. Another
Erase Suspend command can be written after the device has resumed erasing.
