ERASE SUSPEND:
The Erase Suspend command allows sector-erase interruption to
read or program data in another sector of memory. Once the sector erase process
starts, writing the sector erase suspend command requests that the WSM suspend the
sector erase sequence at a predetermined point in the algorithm. The device outputs
status register data when read after the sector erase suspend command is written. Poll-
ing the status register can help determine when the sector erase operation was
suspended. After a successful suspend, a Read Array command can be written to read
data from a sector other than the suspended sector. A program command sequence
may also be issued during erase suspend to program data in sectors other than the sec-
tor currently in the erase suspend mode.
The other valid commands while sector erase is suspended include Read Status Regis-
ter and Sector Erase Resume. After a Sector Erase Resume command is written, the
WSM will continue the sector erase process. V
PP
must remain at V
PPH1/2
(the same V
PP
level initially used for sector erase) while sector erase is suspended. RST or INIT must
also remain at V
IH
. Sector erase cannot resume until program operations initiated during
sector erase suspend have completed.
PROGRAM SUSPEND:
The Program Suspend command allows program interruption
to read data in other memory locations. 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 written. Polling the status regis-
ter 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
PP
must remain at V
PPH1/2
(the same
V
PP
level used for program) while in program suspend mode. RST or INIT must also
remain at V
IH
.
READ STATUS REGISTER:
The status register may be read to determine when a sec-
tor 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 sta-
tus register until another valid command is written. The Read Status Register command
functions independently of the V
PP
voltage.
CLEAR STATUS REGISTER:
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 indi-
cate various failure conditions. The Clear Status Register command functions
independently of the applied V
PP
voltage.
