R68C552 Overview
The Rockwell CMOS R68C552 Dual Asynchronous munications Interface Adapter (DACIA) provides an easily implemented, program controlled two-channel interface between 16-bit microprocessor-based systems and serial munication data sets and modems. The DACIA is designed for maximum programmed control from the microprocessor (MPU) to simplify hardware implementation. Dual sets of registers allow independent control and...
