Detailed explanation-1: -Explanation: RXRDY(Receiver ready output) may be used either to interrupt the CPU or polled by the CPU.
Detailed explanation-2: -An interrupt request (IRQ) is a signal sent to a computer’s processor to momentarily stop (interrupt) its operations. The signal is usually sent by a hardware device to interrupt the processor so the device gets some time to run its own operation.
Detailed explanation-3: -Simplex is the data transmission mode in which the data can flow only in one direction, i.e., the communication is unidirectional. In this mode, a sender can only send data but can not receive it.
Detailed explanation-4: -An active-low signal at this pin shows that the 8251 is now ready to accept the data from the processor. RTS: It stands for the request to send. A low signal shows an assertion for data transmission.
Detailed explanation-5: -Data Output command-A data output command causes the interface to respond by transferring data from the bus into one of its registers.
