20.2. Operation
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 mechanisms operate on the page, sector and full-memory
levels.
The Flow Chart in Figure 54 displays basic Flash Controller operation. The sections that
follow provide details about the various operations (Lock, Unlock, Byte Programming,
Page Protect, Page Unprotect, Page Select Page Erase and Mass Erase) shown in
Figure 54.
