Working Principles

The TL16C754BFN operates by receiving and transmitting serial data through its UART channels. When data is received, it is stored in the corresponding FIFO buffer. The CPU can then retrieve the data from the buffer at its convenience. Similarly, when data needs to be transmitted, it is written to the appropriate FIFO buffer and sent out through the UART channel.

The TL16C754BFN also supports interrupt generation, allowing the CPU to be notified when specific events occur, such as the arrival of new data or the completion of a transmission. This feature helps optimize data handling and reduces the CPU's continuous involvement in the communication process.
