PRELIMINARY
DESCRIPTION
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 monitoring of each channel. (
Transmitter and Receiver bit rates may be controlled by an internal baud rate generator or external times 16 clocks. The baud rate...
