5. MICROPROCESSOR

5-1. System Outline

The system microprocessor has features as shown below.

In considering easy maintenance for specification modification, etc., the program content is written in the built-in non-volatile memory.

The program is also developed in considering use of structured notation, parts modularity, and multi filling system.

Major functions of the system microprocessor are as follows.
