operation using the DQ7 or DQ6 status bits, just as in the standard Word Program
operation. Refer to the Write Operation Status section for more information.
In the erase-suspend-read mode, the system can also issue the autoselect com-
mand sequence. 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. Refer to the Secured Silicon Sec-
tor Addresses and the Autoselect Command Sequence sections for details.
To resume the sector erase operation, the system must write the Erase Resume
command (address bits are don’t care). The bank address of the erase-sus-
pended bank is required when writing this command. Further writes of the
Resume command are ignored. Another Erase Suspend command can be written
after the chip has resumed erasing.
If the Persistent Sector Protection Mode Locking Bit is verified as programmed
without margin, the Persistent Sector Protection Mode Locking Bit Program Com-
mand should be reissued to improve program margin. If the Secured Silicon
Sector Protection Bit is verified as programmed without margin, the Secured Sil-
icon Sector Protection Bit Program Command should be reissued to improve
program margin.
to determine whether the PPB has been programmed with margin. If the PPB has
been programmed without margin, the program command should be reissued to
improve the program margin. Also note that the total number of PPB program/
erase cycles is limited to 100 cycles. Cycling the PPBs beyond 100 cycles is not
guaranteed.
After erasing the PPBs, two additional cycles are needed to determine whether
the PPB has been erased with margin. If the PPBs has been erased without mar-
gin, the erase command should be reissued to improve the program margin. The
programming of either the PPB or DYB for a given sector or sector group can be
verified by writing a Sector Protection Status command to the device.
Note that there is no single command to independently verify the programming
of a DYB for a given sector group.
