QUERY COMMAND AND COMMON FLASH INTERFACE (CFI) MODE
MX29LV400C/MX29LV800C/MX29LV160C T/B features CFI mode. Host system can retrieve the operating char-
acteristics, structure and vendor-specified information such as identifying information, memory size, byte/word
configuration, operating voltages and timing information of this device by CFI mode. If the system writes the CFI
Query command "98h", to address "55h"/"AAh" (depending on Word/Byte mode), the device will enter the CFI
Query Mode, any time the device is ready to read array data. The system can read CFI information at the ad-
dresses given in Table4.
Once user enters CFI query mode, user can not issue any other commands except reset command. The reset
command is required to exit CFI mode and go back to the mode before entering CFI. The system can write the
CFI Query command only when the device is in read mode, erase suspend, standby mode or automatic select
mode.
