than Sector Erase(30H) or Erase Suspend(B0H) during
the time-out period resets the device to read mode.
ERASE SUSPEND
This command only has meaning while the state ma-
chine is executing Automatic Sector Erase operation, and
therefore will only be responded during Automatic Sector
Erase operation. When the Erase Suspend command is
issued during the sector erase operation, the device re-
quires a maximum 20us to suspend the sector erase
operation. However, When the Erase Suspend command
is written during the sector erase time-out, the device
immediately terminates the time-out period and suspends
the erase operation. After this command has been ex-
ecuted, the command register will initiate erase suspend
mode. The state machine will return to read mode auto-
matically after suspend is ready. At this time, state ma-
chine only allows the command register to respond to the
Erase Resume, program data to, or read data from any
sector not selected for erasure.
The system can determine the status of the program
operation using the Q7 or Q6 status bits, just as in the
standard program operation. After an erase-suspend pro-
gram operation is complete, the system can once again
read array data within non-suspended blocks.
ERASE RESUME
This command will cause the command register to clear
the suspend state and return back to Sector Erase mode
but only if an Erase Suspend command was previously
issued. Erase Resume will not have any effect in all
other conditions. Another Erase Suspend command can
be written after the chip has resumed erasing.
QUERY COMMAND AND COMMON FLASH
INTERFACE (CFI) MODE
MX29LV640BT/BB is capable of operating in the CFI
mode. This mode all the host system to determine the
manufacturer of the device such as operating parameters
and configuration. Two commands are required in CFI
mode. Query command of CFI mode is placed first, then
the Reset command exits CFI mode. These are described
in Table 3.
The single cycle Query command is valid only when the
device is in the Read mode, including Erase Suspend,
Standby mode, and Read ID mode; however, it is ignored
otherwise.
The Reset command exits from the CFI mode to the Read
mode, or Erase Suspend mode, or read ID mode. The
command is valid only when the device is in the CFI
mode.
