QUERY COMMAND AND COMMON FLASH INTERFACE (CFI) MODE
MX29LV033C features CFI mode. Host system can retrieve the operating characteristics, structure and vendor-
specified information such as identifying information, memory size, operating voltages and timing information of this
device by CFI mode. The device enters the CFI Query mode when the system writes the CFI Query command, 98H,
to address XXH any time the device is ready to read array data. The system can read CFI information at the ad-
dresses given in Table 4. A reset command is required to exit CFI mode and go back to ready array mode or erase
suspend mode. The system can write the CFI Query command only when the device is in read mode, erase suspend,
standby mode or automatic select mode.
