10.3.2.3.3 Flash Multi-Page Erase Mode
The Multi-Page Erase (FLMPERn) mode will allow each write to the memory array to erase multiple pages. When enabling FLMPERn, you can select between erasing 2, 4, 8, 16, or 32 pages.
The LSbs of the page address are ignored when defining which Flash pages are erased. Using
FLMPER4 as an example, erasing any page in the 0x08 -
0x0B range will cause the erase of all pages in the range.
| CMD | Pages Erased | Description |
|---|---|---|
| FLMPER2 | 2 | Pages matching FPAGE[N:1] are erased. The value in FPAGE[0] is ignored. |
| FLMPER4 | 4 | Pages matching FPAGE[N:2] are erased. The value in FPAGE[1:0] is ignored. |
| FLMPER8 | 8 | Pages matching FPAGE[N:3] are erased. The value in FPAGE[2:0] is ignored. |
| FLMPER16 | 16 | Pages matching FPAGE[N:4] are erased. The value in FPAGE[3:0] is ignored. |
| FLMPER32 | 32 | Pages matching FPAGE[N:5] are erased. The value in FPAGE[4:0] is ignored. |
Note: FPAGE is the page number when doing a
Flash erase. Refer to the Flash Addressing for Self-Programming section for
details.
