Working Principles

The SC16C654BIBS,551 operates as a serial communication controller by providing multiple UART channels. Each channel consists of a transmitter (TX) and a receiver (RX) along with associated control signals. The controller communicates with external devices through these channels using asynchronous serial communication.

Data is transmitted and received in the form of individual bits, which are synchronized using start and stop bits. The controller handles data buffering, interrupt generation, and flow control to ensure reliable data transfer.
