Question 29 (2 points) C is the carry flag Op=1 is addition Op=O is subtraction A is the first operand, B is the 2nd operand. Select a Boolean expression that could accurately describe the logic in which the carry flag is set to 1, according to the correct operation of the ALU in a Cortex- M4 processor, with the given Op codes. Note: Focus only on the MSB of A and B. Ignore any bitwise operations from previous bits (30->0). C = OpA + AB + p C=,B+ AB + O A C=0B + AB + OpA C =0,B+ AB + , A
