Data

She e t

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 31 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.
