WebASYNCHRONOUS OPERATION The USART uses two I/O pins to transmit and receive serial data. Because there is no separate clock signal for asynchronous operation, one pin (TX) is used for transmission and the other pin (RX) is used for recep-tion. Both transmission and reception can occur at the same time and this is known as ‘full duplex ... WebHDLC uses synchronous transmission. All transmissions are in frames, and a single frame format suffices for all types of data and control exchanges. ... Asynchronous transmission is simple and easy to implement but it has high overhead. For example, to transmit a 7-bit character, 4 additional bits are sent leading to poor throughput or ...
