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