- Q1- Write a program in assembly language for the 8085 microprocessor to send one byte of data located at the memory address (3000H ) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz . When sending the required byte, you must adhere to the following: The two high bits of the start bits(1 1) must be sent, after that the data bits are sent, after that the low bit of the stop bit (0) is sent. The following flowchart will help you. The solution must be integrated and include the calculation of the baudrate delay timeAssembly Language x86: a procedure called "SubtractThenAdd" which does the following: takes the EAX, EBX, and ECX registers as arguments computes this value: EAX = (EAX - ECX) + EBX returns the result inside of EAX uses PUSH and POP instructions or the USES operator to ensure that EBX and ECX retain their original values after the procedure You must include the entire procedure definition, from the PROC directive to the ENDP directive. Do not define or use any additional variables or registers other than EAX, EBX, and ECX.Remaining Time: 28 minutes, 56 seconds.

- Multiple Choice Statement: In the Integer division block, the width of the quotient register cannot be the same size as that of the divisor or the dividend. Select the best answer that correctly gives the reason if the above statement is true or false False: The quotient registers needs to be the same size as that of the dividend, as this number could be equal to the dividend False: The quotient width needs to be equal to the sum of the widths of the divisor and the dividend, else there will be an overflow True: The width of the quotient has to be 32 bits no matter the size of the divisor or dividend True: The width of the quotient register is always going to be smaller than the dividend or divisor, since we are dividing. So the quotient register always needs to be smaller in widthQ1\ 1- Write a program in assembly language for the 8085 microprocessor to send 10 bytes of data located at the memory address (3000h) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz. And two high pulses must be sent before each byte (start bits) and one low pulse after each byte (end bits). You can use this flowchart, but you should notice that this flowchart deals with one byte, and you are required to deal with 10 bytes Transmit No Set up Character Bit Counter Send Start Bit Wait Bit Time Get Character in Accumulator Output Bit Using Do Wait Bit Time Rotate Next Bit in Do Decrement Bit Counter Is It Last Bit?
