| 3 | * This is an older type of interface for self programming flash. It is | ||
| 4 | * commonly use in older AMD chips and is obsolete compared with CFI. | ||
| 5 | * It is called JEDEC because the JEDEC association distributes the ID codes | ||
| 6 | * for the chips. | ||

| 8 | * See the AMD flash databook for information on how to operate the interface. | ||
