4. (25 points) Write a subroutine Design and write an MSP430 assembly language subroutine UINTdivUINT performs integer division on unsigned integers. It accepts input parameters, a dividend and a divisor, and returns the quotient and remainder (all 16-bit unsigned integers). The input parameters are pushed onto the stack and the output operands are returned through the stack. For example, when dividend =42, divisor =14, the quotient =3 and the remainder =0. The main program is given below. The quotient is stored in PAOUT (P1OUT\&P2OUT) and the remainder is stored in PBOUT(P3OUT\&P4OUT)
