Working Principles

The TL16C2552FNR operates based on the principles of UART communication. It uses start and stop bits to frame each character and asynchronous timing to synchronize data transmission between the sender and receiver. The UART receives parallel data from the microcontroller, converts it into a serial format, and transmits it over the communication line. On the receiving end, the UART receives the serial data, converts it back to parallel format, and sends it to the microcontroller.
