Program Suspend
Read Status Register
Clear Status Register
The Program Suspend command allows program interruption to read data in other memory loca-
tions. Once the program process starts, writing the Program Suspend Command requests that
the WSM suspend the program sequence at a predetermined point in the algorithm. The device
continues to output status register data when read after the program suspend command is writ-
ten. Polling the status register can help determine when the program operation was suspended.
After a successful suspend, a Read Array command can be written to read data from locations
other than that which is suspended. The only other valid commands while program is suspended
are Read Status Register and Program Resume. V
used for program) while in program suspend mode. RST or INIT must also remain at V
The status register may be read to determine when a sector erase or program completes and
whether the operation completed successfully. The status register may be read at any time by
writing the Read Status Register command. After writing this command, all subsequent read
operations will return data from the status register until another valid command is written. The
Read Status Register command functions independently of the V
Error flags in the status register can only be set to “1”s by the WSM and can only be reset by the
Clear Status Register command. These bits indicate various failure conditions. The Clear Status
Register command functions independently of the applied V
