How many T-states are required to execute the following instruction? MVI A,16H A) 4 T-states B) 7 T-states C) 10 T-states D) 14 T-states
Question
How many T-states are required to execute the following instruction? MVI A,16H A) 4 T-states B) 7 T-states C) 10 T-states D) 14 T-states
Solution
The instruction MVI A,16H is a 2-byte instruction. In the 8085 microprocessor, the opcode fetch cycle takes 4 T-states and the memory read cycle takes 3 T-states. Therefore, the total number of T-states required to execute this instruction is 4 + 3 = 7 T-states. So, the correct answer is B) 7 T-states.
