Data Memory

space.
Flash Information Area
Table 7 lists the F0823 Series Flash Information Area. This 128 B Information Area is
accessed by setting bit 7 of the Flash Page Select Register to 1. When access is enabled,
the Flash Information Area is mapped into the Program Memory and overlays the 128
bytes at addresses FE00H to FF7FH. When the Information Area access is enabled, all
reads from these Program Memory addresses return the Information Area data rather than
the Program Memory data. Access to the Flash Information Area is read-only.
