APPENDIX A. COMMON FLASH INTERFACE - CFI
The Common Flash Interface is a JEDEC ap-
proved, standardized data structure that can be
read from the Flash memory device. It allows a
system software to query the device to determine
various electrical and timing parameters, density
information and functions supported by the mem-
ory. The system can interface easily with the de-
vice, enabling the software to upgrade itself when
necessary.
When the CFI Query Command (RCFI) is issued
the device enters CFI Query mode and the data
the data.
Table 25. Query Structure Overview
Note: 1. Offset 15h defines P which points to the Primary Algorithm Extended Query Address Table.
2. Offset 19h defines A which points to the Alternate Algorithm Extended Query Address Table.
Table 26. CFI - Query Address and Data Output
Note: 1. The x8 or Byte Address and the x16 or Word Address mode are not available.
2. Query Data are always presented on DQ7-DQ0. DQ31-DQ8 are set to '0'.
