Flash Information Area
PS025203-0405
The eZ8 CPU supports 64KB of Program Memory address space. The Z8 Encore!
Z8F0823 Series devices contain 8KB of on-chip Flash memory in the Program Memory
address space. Reading from Program Memory addresses outside the available Flash
memory addresses returns
addresses produces no effect. Table 6 describes the Program Memory Maps for the Z8

address space.
Table 7 describes the Z8 Encore!
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
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.
