Abstract

A single-chip microcomputer comprises a CPU (1), a RAM (2), a ROM (3), a timer (4), serial I/O communication logic (5), and four I/O ports (11-14). The serial I/O communication logic is capable of handling serial communications in either the NRZ or Manchester (biphase) format. The result is more versatile and more reliable serial communications.
