1-39 Universal Asynchronous Receiver Transmitter (UART) After 8 bits are transmitted, D must go high for at least one bit time When receiving, the UART detects the start bit, receives the 8 data bits, and converts the data to parallel form when it detects the stop bit The UART must synchronize the incoming bit stream with the local clock n The number of bits transmitted per second is often referred to the BAUD rate After 8 bits are transmitted, D must go high for at least one bit time When receiving, the UART detects the start bit, receives the 8 data bits, and converts the data to parallel form when it detects the stop bit The UART must synchronize the incoming bit stream with the local clock n The number of bits transmitted per second is often referred to the BAUD rate
