Working Principles

The TL16C452FNR operates based on the principles of UART communication. It receives serial data from a transmitting device, converts it into parallel form, and then transmits it to the receiving device. Similarly, it receives parallel data from the receiving device, converts it into serial form, and transmits it back to the transmitting device.

The UART communication is asynchronous, meaning that the timing of data transmission is not dependent on a clock signal. Instead, start and stop bits are used to indicate the beginning and end of each data frame.
