Figure 84. Flash Memory Arrangement
The Flash Controller programs and erases the Flash memory. The Flash Controller pro-
vides the proper Flash controls and timing for byte programming, Page Erase, and Mass
Erase of the Flash memory. The Flash Controller contains a protection mechanism, via the
Flash Control register (FCTL) to prevent accidental programming or erasure. The Flow
Chart in Figure 85 illustrates basic Flash Controller operation. The following subsections
provide details on the various operations (Lock, Unlock, Byte Programming, Page Erase,
and Mass Erase) listed in Figure 85.
