It supports standard asynchronous protocol with : 5 to 8 Bit character format odd, even or no parity generation and detection c) Baud rate from DC to 19.2 Kbaud False […]

8251 Serial Interface

8251 Serial Interface: Most of the microprocessors are designed for parallel communication. In parallel communication number of lines required to transfer data depend on the number of bits to be transferred. For example, to transfer a byte of data, 8 lines are required and all 8 bits are transferred simultaneously. Thus for transmitting data over […]
