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.

Sector Protection/Unprotection

The hardware sector protection feature disables both program and erase operations in any sector. The

hardware sector unprotection feature re-enables both program and erase operations in previously

protected sectors.

Sector protection/unprotection must be implemented using programming equipment. The procedure re-

quires a high voltage (VID) on address pin A9 and the control pins. Contact Eon Silicon Solution, Inc. for

an additional supplement on this feature.
