4.5 Flash Memory Map
Figure 4-1
Flash Memory is divided into three functional blocks. The Program and boot memories reside on the
Program Memory buses. They are controlled by one set of banked registers. Data Memory Flash resides
on the Data Memory buses and is controlled separately by its own set of banked registers.
The top nine words of the Program Memory Flash are treated as special memory locations. The content of
these words is used to control the operation of the Flash controller. Because these words are part of the
Flash Memory content, their state is maintained during power-down and reset. During chip initialization,
the content of these memory locations is loaded into Flash Memory control registers, detailed in the Flash
Memory chapter of the 56F8300 Peripheral User Manual. These configuration parameters are located
between $00_3FF7 and $00_3FFF.
