2.1 Introduction
The central processor unit (CPU08) can address 64 Kbytes of memory space. The memory map, shown
in
2.2 Unimplemented Memory Locations
Accessing an unimplemented location can have unpredictable effects on MCU operation. In
and in register figures in this document, unimplemented locations are shaded.
2.3 Reserved Memory Locations
Accessing a reserved location can have unpredictable effects on MCU operation. In
register figures in this document, reserved locations are marked with the word Reserved or with the
letter R.
