Working Principles

The XR16C854CQTR-F operates based on the principles of UART communication. It receives and transmits asynchronous serial data using start and stop bits. The integrated FIFOs provide buffering capabilities, reducing the need for constant CPU intervention.

When receiving data, the UART continuously monitors the serial input line for start bits. Once a start bit is detected, it samples the incoming data at regular intervals and stores it in the receive FIFO. The CPU can then read the received data from the FIFO at its convenience.

During transmission, the UART retrieves data from the transmit FIFO and sends it out through the serial output line. It adds the necessary start and stop bits to each byte of data before transmission.
