Memory
2.1 Introduction
The central processor unit (CPU08) can address 64 Kbytes of memory space. The memory map, shown
in
Figure
2-1.
2.2 Unimplemented Memory Locations
Executing code from an unimplemented location will cause an illegal address reset. In
Figure
2-1,
unimplemented locations are shaded.
2.3 Reserved Memory Locations
Accessing a reserved location can have unpredictable effects on MCU operation. In
Figure
2-1, register
locations are marked with the word Reserved or with the letter R.
2.4 Direct Page Registers
Figure 2-2
shows the memory mapped registers of the MC68HC908QYA/QTA Family. Registers with
addresses between $0000 and $00FF are considered direct page registers and all instructions including
those with direct page addressing modes can access them. Registers between $0100 and $FFFF require
non-direct page addressing modes. See
Chapter 7 Central Processor Unit (CPU)
for more information on
addressing modes.
