15.1
Common Flash Memory Interface
The Common Flash Interface (CFI) specification outlines device and host system software inter-
rogation 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-indepen-
dent, 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 in-
formation at the addresses given in Tables
15.3–15.6
) within that bank. All reads outside of the
CFI address range, within the bank, returns 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
S pansion Low Lev el Driv er User’s Guide
( available on www.amd.com and
www.fujitsu.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 refer to the CFI Specification (see JEDEC publications JEP137-A
and JESD68.01and CFI Publication 100). Please contact your sales office for copies of these
documents.
