QUERY COMMAND AND COMMON FLASH
INTERFACE(CFI) MODE
MX29LV017A is capable of operating in the CFI mode.
This mode all the host system to determine the manu-
facturer 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 Automatic Select mode; however, it
is ignored otherwise.
The Reset command exits from the CFI mode to the
Read mode, or Erase Suspend mode, or Automatic Se-
lect mode. The command is valid only when the device
is in the CFI mode.
