Central Processor Unit (CPU)
MOTOROLA
Central Processor Unit (CPU)
4.2 Introduction
The central processor unit (CPU) consists of a CPU control unit, an
arithmetic/logic unit (ALU), and five CPU registers. The CPU control unit
fetches and decodes instructions. The ALU executes the instructions.
The CPU registers contain data, addresses, and status bits that reflect
the results of CPU operations.
4.3 Features
Features of the CPU include:
4.0-MHz Bus Frequency on Standard Part
8-Bit Accumulator
8-Bit Index Register
11-Bit Program Counter
6-Bit Stack Pointer
Condition Code Register with Five Status Flags
62 Instructions
8 Addressing Modes
Power-Saving Stop, Wait, Halt, and Data-Retention Modes
