WebRxRDY O Receiver ready: When high, alert the MP8080A that the receiver contains a data character that is ready to be input to the CPU. The RxRDY output, which is automatically reset whenever a character is read from the MP8251, can be used as an interrupt to the system. For polled operation, the condition of the RxRDY signal can be tested by WebDec 17, 2014 · RxRDy is automatically reset to logic 0 when the MPU reads the contents of the receive_data register. Through software, the 8251A can be set up to internally divide theClock signal input at Rxc by 1, 16, or 64 to obtain the desired baud rate.
WebHowever, the RXD input is kept low during the stop bit period. In the Hades simulation model of the 8251, the receiver still asserts RXRDY despite the missing stop bit.
