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 includes a shift register (RBA-RBH, FIG. 8J) to separate the data and clock signals in a Manchester-encoded data stream. The Manchester encoding is adaptable to any data rate simply by changing the frequency of a high speed clock associated with the shift register.
