4.5 Flash Memory Map
Figure 4-1 illustrates the Flash Memory (FM) map on the system bus.
The Flash Memory is divided into three functional blocks. The Program and boot memories reside on the
1. Two words are allocated for each entry in the vector table. This does not allow the full address range to be referenced
from the vector table, providing only 19 bits of address.
2. If the VBA is set to 0200 (or VBA = 0000 for Mode 1, EMI_MODE = 0), the first two locations of the vector table are the
chip reset addresses; therefore, these locations are not interrupt vectors.
