BLOCK STRUCTURE
The main flash memory array can be organized as 2M Words. The details of the address ranges and the cor-
responding sector addresses are shown in Table 1-1 & 1-2. Table 1-1 shows the sector group architecture for the
Top Boot part, whereas Table 1-2 shows the sector group architecture for the Bottom Boot part. The specific se-
curity sector addresses are shown at the bottom off each of these tables.
