Sector Erase time-out immediately terminates the time-out period and suspends  
the erase operation. Addresses are don’t-cares when writing the Erase Suspend  
command.  
When the Erase Suspend command is written during a sector erase operation, the  
device requires a maximum of 20 µs to suspend the erase operation. However,  
when the Erase Suspend command is written during the sector erase time-out,  
the device immediately terminates the time-out period and suspends the erase  
operation.  
After the erase operation is suspended, the system can read array data from or  
program data to any sector not selected for erasure. (The device erase suspends  
all sectors selected for erasure.) Normal read and write timings and command  
definitions apply. Reading at any address within erase-suspended sectors pro-  
duces status data on DQ7–DQ0. The system can use DQ7, or DQ6 and DQ2  
together, to determine if a sector is actively erasing or is erase-suspended. See  
Write Operation Status, on page 27 for information on these status bits.  
After an erase-suspended program operation is complete, the system can once  
again read array data within non-suspended sectors. The system can determine  
the status of the program operation using the DQ7 or DQ6 status bits, just as in  
the standard program operation. See Write Operation Status, on page 27 for  
more information.  
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 Com-  
mand Sequence, on page 20 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 resumes erasing.
