The following FIVE instructions were executed on an 8085 microprocessor.
MVI A, 33H
MVI B, 78H
ADD B
CMA
ANI 32H
The Accumulator value immediately after the execution of the fifth instruction is
A. 00H
B. 10H
C. 11H
D. 32H
Please scroll down to see the correct answer and solution guide.
Right Answer is: B
SOLUTION
Concept:
MVI → Move immediate data to register
ADD → Contents of operand + content of accumulator & result is stored in the accumulator
CMA → Compliment the contents of the accumulator
ANI → Logically AND the contents of the accumulator with 8-bit data and store data in the accumulator
Calculation:
MVI A, 33H A ← 33H
MVI B, 78H B ← 33H
