Section 6. Central Processor Unit (CPU)

6.1 Introduction

The M68HC08 CPU (central processor unit) is an enhanced and fully

object-code-compatible version of the M68HC05 CPU. The CPU08

Reference Manual (Motorola document order number CPU08RM/AD)

contains a description of the CPU instruction set, addressing modes,

and architecture.

6.2 Features

Feature of the CPU include:

•

Object code fully upward-compatible with M68HC05 Family

•

16-bit stack pointer with stack manipulation instructions

•

16-Bit index register with X-register manipulation instructions

•

8-MHz CPU internal bus frequency

•

64-Kbyte program/data memory space

•

16 addressing modes

•

Memory-to-memory data moves without using accumulator

•

Fast 8-bit by 8-bit multiply and 16-bit by 8-bit divide instructions

•

Enhanced binary-coded decimal (BCD) data handling

•

Modular architecture with expandable internal bus definition for

extension of addressing range beyond 64-Kbytes

•

Low-power stop and wait modes
