Statement: Write a program to output contents of B register LSB to MSB on the SOD pin.

Source program : MVI C, 08H : Initialize count with 8 MOV A, B BACK: RRC : Rotate B register contents right MOV B, A : Save contents of register B JNC SKIP : If no carry skip MVI A, COH SIM : If carry, send high on SOD JMP NEXT SKIP: MVI A, 40H SIM : If no carry, send low on SOD. NEXT: CALL DELAY : Wait for specific time DCR C : Decrement count by 1 JNZ BACK  : if count = 0 Stop, if not repeat HLT : Stop program execution Delay subroutine: Delay: LXI D, Count Back: DCX D MOV A, D ORA E JNZ Back RET
