gram operation. See “Write Operation Status” 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 Command Sequence”
for more information.
The system must write the Erase Resume command
(address bits are “don’t care”) to exit the erase sus-
pend 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.
