Preliminary
4.4 Data Map
4.5 Flash Memory Map
Figure 4-1
illustrates the Flash Memory (FM) map on the system bus.
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.

Two words are allocated for each entry in the vector table. This does not allow the full address range to be referenced from

If the VBA is set to $0200, the first two locations of the vector table will overlay the chip reset addresses.
