Q2. In the microcontroller simulation, what is the function of the clock signal in registers?
a) It performs logical operations
b) It triggers data storage at specific intervals
c) It controls the ALU’s operations
d) It sets the value of status flags
Q3. What happens to the carry flag after an addition operation in the ALU if the result exceeds the register’s maximum value?
a) It is set to one
b) It is reset to zero
c) It remains unchanged
d) It is set to match the input value
Q4. In your simulation, which logic gate outputs a 1 only if all of its inputs are 1?
