General Description

The Rockwell CMOS R68C552 Dual Asynchronous Communications Interface Adapter (DACIA) provides an easily implemented, program controlled two-channel interface between 16-bit microprocessor-based systems and serial communication 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 monitoring of each channel.
