The universal asynchronous receiver-transmitter (UART) takes bytes of data and transmits the individual bits in a sequential fashion. At the destination, a second UART re-assembles the bits into complete bytes. Each UART contains a shift register, which is the fundamental method of conversion between serial and parallel forms. Serial transmission of digital information (bits) through a si…

"WebSep 21, 2015 · Well, there are differences – important ones. The first difference between a USART and a UART is the way in which the serial data may be clocked. A UART generates its data clock internally to the microcontroller and synchronizes that clock with the data stream by using the start bit transition. " - Clocked uart
