1
Outline
The CPU controls the loads in the body and sends and receives data
to and from the various optional controllers through the serial data
communication line and controls the system.

Features
The H8/570 (CPU) is a single-chip microprocessor which performs
the exclusively-used commands at high speeds to strengthen the
routine operations such as the timer functions and the serial com-
munication functions.
