ADVANCED INFORMATION  
Excel Semiconductor inc.  
This device enters the CFI Query mode when the  
system writes the CFI query command, 98h, to  
address 55h in word mode (or address AAh in byte  
mode), any time the device is ready to read array  
data. The system can read CFI information at the  
addresses given in Tables 5-8. To terminate reading  
CFI data, the system must write the reset com-  
mand.The CFI query command can be written to the  
system when the device is in the autoselect mode  
or the erase-suspend-read mode. The device  
enters the CFI query mode, and the system can read  
CFI data at the addresses given in Tables 5-8.  
When the reset command is written, the device  
returns respectively to the read mode or erase-sus-  
pend-read mode.  
Common Flash Memory  
Interface (CFI)  
CFI is supported in the ES29DL320 device. The  
Common Flash Interface (CFI) specification out-  
lines device and host system software interrogation  
handshake, which allows specific vendor-specified  
software algorithms to be used for entire families of  
devices. Software support can then be device-inde-  
pendent, JEDEC ID-independent, and forward- and  
backward-compatible for the specified flash device  
families. Flash vendors can standardize their exist-  
ing interfaces for long-term compatibility.
