MISRA Rule 10.4 only allows the usage of arithmetic operations on operands of the same essential type category. Adding "U" at the end of the integer literals to have same type of operands when an arithmetic operation is performed. This fixes violation where an arithmetic operation is performed on signed and unsigned int types.
