CPU and Peripheral Overview
eZ8 CPU Features
The eZ8, ZiLOG’s latest 8-bit Central Processing Unit (CPU), meets the continuing
demand for faster and more code-efficient microcontrollers. The eZ8 CPU executes a
superset of the original Z8 instruction set. The eZ8 CPU features include:
•
Direct register-to-register architecture allows each register to function as an
accumulator, improving execution time and decreasing the required program memory
