Operation
PS022825-0908
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 pro-
gramming or erasure. These mechanism operate on the page, sector and full-memory lev-
els.
The Flow Chart 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
