17 / 48 page Am29LV017D 19 COMMON FLASH MEMORY INTERFACE (CFI) 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-indepen- dent, JEDEC ID-independent, and forward- and back- ward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h, any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 4–7. To terminate reading CFI data, the system must write the reset command. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Tables 4–7. The system must write the reset command to return the device to the autoselect mode. For further information, please refer to the CFI Specifi- cation and CFI Publication 100, available via the World Wide Web at http://www.amd.com/products/nvd/over- view/cfi.html. Alternatively, contact an AMD represen- tative for copies of these documents. Table 4.
