Program Suspend/Program Resume Command Sequence
Note
See
The Program Suspend command allows the system to interrupt a programming operation or a Write to Buffer
programming operation so that data can be read from any non-suspended sector. When the Program
Suspend command is written during a programming process, the device halts the program operation within
20 μs maximum and updates the status bits. Addresses are not required when writing the Program Suspend
command.
After the programming operation is suspended, the system can read array data from any non-suspended
sector. The Program Suspend command may also be issued during a programming operation while an erase
is suspended. In this case, data may be read from any addresses not in Erase Suspend or Program Suspend.
If a read is needed from the Secured Silicon Sector area (One-time Program area), then user must use the
proper command sequences to enter and exit this region. Note that the Secured Silicon Sector, autoselect,
and CFI functions are unavailable when a program operation is in progress.
The system may also write the autoselect command sequence when the device is in the Program Suspend
mode. The system can read as many autoselect codes as required. When the device exits the autoselect
mode, the device reverts to the Program Suspend mode, and is ready for another valid operation. See
Autoselect Command Sequence on page 42
After the Program Resume command is written, the device reverts to programming. 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
The system must write the Program Resume command (address bits are don’t care) to exit the Program
Suspend mode and continue the programming operation. Further writes of the Resume command are
ignored. Another Program Suspend command can be written after the device resumes programming.
