13. Common Flash Memory Interface
The Common Flash Interface (CFI) specification outlines device and host system software interrogation
handshake, which allows specific vendor-specified soft-ware algorithms to be used for entire families of
devices. Software support can then be device-independent, 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
(BA)555h any time the device is ready to read array data. The system can read CFI information at the
addresses given in Tables
12.3
–
12.6
) within that bank. All reads outside of the CFI address range, within the
bank, return non-valid data. Reads from other banks are allowed, writes are not. To terminate reading CFI
data, the system must write the reset command.
The following is a C source code example of using the CFI Entry and Exit functions. Refer to the
Spansion
Low Level Driver User’s Guide
(available at
www.spansion.com
) for general information on Spansion Flash
memory software development guidelines.
/* Example: CFI Entry command */
*((UINT16 *)bank_addr + 0x555) = 0x0098; /* write CFI entry command */
/* Example: CFI Exit command */
*((UINT16 *)bank_addr + 0x000) = 0x00F0; /* write cfi exit command */
For further information, please see the CFI Specification (see JEDEC publications JEP137-A and
JESD68.01and CFI Publication 100). Please contact your sales office for copies of these documents.
