Section 2. Memory Map

2.1 Introduction

The CPU08 can address 64k-bytes of memory space. The memory map,

shown in Figure 2-1, includes:

•

62,368 bytes of user FLASH — MC68HC908AP64

32,768 bytes of user FLASH — MC68HC908AP32

16,384 bytes of user FLASH — MC68HC908AP16

8,192 bytes of user FLASH — MC68HC908AP8

•

2,048 bytes of RAM — MC68HC908AP64 and MC68HC908AP32

1,024 bytes of RAM — MC68HC908AP16 and MC68HC908AP8

•

48 bytes of user-defined vectors

•

959 bytes of monitor ROM

2.2 Unimplemented Memory Locations

Accessing an unimplemented location can cause an illegal address

reset if illegal address resets are enabled. In the memory map

(Figure 2-1) 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 the Figure 2-1 and in register figures in this document,

reserved locations are marked with the word Reserved or with the

letter R.
