Data Memory
The Z8 Encore! F0830 Series does not use the eZ8 CPU’s 64 KB data memory address
space.
Flash Information Area
Table 7 maps the Z8 Encore! F0830 Series Flash information area. The 128-byte informa-
tion 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 program memory and overlays these
128 bytes at addresses FE00H to FE7FH. When information area access is enabled, all
reads from these program memory addresses return information area data rather than pro-
gram memory data. Access to the Flash information area is read-only.
