Unformatted text preview: asynchronous characters containing 8 data bits, 1 1 2 stop bits, and even parity. The baud rate factor is to be 16. Let the even address associated with the 8251A be 1060H. Extend the sequence so that it outputs a command that clears the error bits and enables the receiver only and not the transmitter. 3. Write an instruction sequence to use the 8251A set up in Problem 2 to input a 50 byte sequence, by program-controlled I/O, storing it in array GOLD in memory. After completing the input sequence, if a parity or overrun error occurred, then repeat the entire input sequence after clearing the error bits....
