Program Suspend/Program Resume Command Sequence
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 15
µs maximum (5µs typical) and updates the status bits. Addresses are not re-
quired when writing the Program Suspend command.
After the programming operation has been 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 SecSi Sector area (One-time Program
area), then user must use the proper command sequences to enter and exit this
region. Note that the SecSi Sector autoselect, and CFI functions are unavailable
when 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 for more information.

mand sequence.
