Operation
PS024314-0308
The Flash Controller programs and erases Flash memory. The Flash Controller provides
the proper Flash controls and timing for Byte Programming, Page Erase, and Mass Erase
of Flash memory.
The Flash Controller contains several protection mechanisms to prevent accidental
programming or erasure. These mechanism operate on the page, sector and full-memory
levels.
The Flowchart in
sections provide details about the various operations (Lock, Unlock, Byte Programming,
Page Protect, Page Unprotect, Page Select Page Erase, and Mass Erase) displayed in
Figure
21.
