The language needed is assembly language 8086

3) The following questions are set up in view of the Figures (d,e) a) Describe what type of 1/0 operation is carried out in Figure (d). What are the addresses of data lines, strobe output and busy input in the circuit. Assume that all unused address bits are zero. b) Write a program that will implement the sequence in Figure (e) for the circuit in Figure (d). Character data are held in memory starting at address PRNT_BUFF and the number of characters held in the buffer is identified by the count at address CHAR-COUNT. Write comments and Use minimum number of instructions. ALE AA AD, AD, ADAS CLK 74373 (2) Address atch OE D A CLK 0 0 D D CBA P P. do 47138 WO do address decoder O'M Do 743730 Port 0 0 A OE 0.
