Data Memory
The Z8 Encore!
®
64K Series does not use the eZ8 CPU’s 64KB Data Memory address
space.
Information Area
®
64K Series Information Area. This 512 byte Informa-
tion Area is accessed by setting bit 7 of the Page Select Register to 1. When access is
enabled, the Information Area is mapped into the Program Memory and overlays the 512
bytes at addresses
FE00H
to
FFFFH
. When the Information Area access is enabled, execu-
tion of LDC and LDCI instruction from these Program Memory addresses return the Infor-
mation Area data rather than the Program Memory data. Reads of these addresses through
the On-Chip Debugger also returns the Information Area data. Execution of code from
these addresses continues to correctly use the Program Memory. Access to the Information
Area is read-only.
