What is the difference between UART and USART communication?
|
|
they are the names of the same particular thing, just the difference of A and S is there in it
|
|
|
one uses asynchronous means of communication and the other uses synchronous means of communication
|
|
|
one uses asynchronous means of communication and the other uses asynchronous and synchronous means of communication
|
|
|
one uses angular means of the communication and the other uses linear means of communication

Explanation:
Detailed explanation-1: -In “synchronous mode, ‘’ the baud rate will be the same as the frequency of TXC. In “asynchronous mode", it is possible to select the baud rate factor by mode instruction. It can be 1, 1/16 or 1/64 the TXC. The falling edge of TXC sifts the serial data out of the 8251.
