Flash Protection
For example, if you have a Flash data table that can be changed using a Flash write routine, you
might have assembly code that looks like this:
area Table (ROM, ABS)
org 3C80h
widgetTable:
export WidgetTable
db 57h ; W
db 49h ; I
db 44h ; D
db 47h ; G
db 45h ; E
db 54h ; T
; …. More table entries continue
You then unprotect the Flash block associated with this table at address 3C80h and make your
change in the flashsecurity.txt file as shown in Figure 8-4.
