After the erase operation has been suspended, the bank enters the erase-suspend-read mode.
The system can read data from or program data to any sector not selected for erasure. (The de-
vice
erase suspends
all sectors selected for erasure.) Reading at any address within erase-
suspended sectors produces status information 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. Refer to
Table 8.23
for information on these status bits.
After an erase-suspended program operation is complete, the bank returns to the erase-suspend-
read mode. The system can determine the status of the program operation using the DQ7 or DQ6
status bits, just as in the standard program operation.
In the erase-suspend-read mode, the system can also issue the Autoselect command sequence.
See
Write Buffer Programming
and
Autoselect
for details.
To resume the sector erase operation, the system must write the Erase Resume command. The
bank address of the erase-suspended 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.
The following is a C source code example of using the erase suspend function. Refer to the
Spansion Low Level Driver User’s Guide
(available on
www.amd.com
and
www.fujitsu.com
)
for general information on Spansion Flash memory software development guidelines.
/* Example: Erase suspend command */
*( (UINT16 *)bank_addr + 0x000 ) = 0x00B0; /* write suspend command */

Program Suspend/ Program Resume Commands
The Program Suspend command allows the system to interrupt an embedded programming op-
eration or a
Write to Buffer
programming operation so that data can read from any non-
suspended sector. When the Program Suspend command is written during a programming pro-
cess, the device halts the programming operation within t
PSL
(program suspend latency) and
updates the status bits. Addresses are
don't-cares
when writing the Program Suspend command.
