Intro Microprocessor System (CDA 3331C)

MSP430G2553 Microprocessor Used

**TYPE THE SOLUTION PLEASE**

An example of an assembly program is given below:

.cdecls C,LIST,"msp430.h"

.text .retain .retainrefs

RESET mov.w #WDTPW|WDTHOLD,WDTCTL mov.w #__STACK_END,SP mov.w #007Dh,&0200h ;the first number mov.w #00B5h,&0202h ;the second number mov.w #00E8h,&0204h ;the third number

jmp $

;------------------------ ;Stack Pointer definition ;------------------------ .global __STACK_END .sect .stack ;------------------- ;Interrupt Vectors ;------------------- .sect RESET_VECTOR .short RESET .end

I was given this, I dont think its correct since its not in an assembly program, here it is:

7.2

Part: A

MVI A, 2H ;Copy value 2H in register A

MVI B, 4H ;Copy value 4H in register B

DATA SEGMENT

NUM1 DB 8H

NUM2 DB 8H

SUM DB ?

ENDS

CODE SEGMENT

ASSUME DS:DATA CS:CODE

START:

MOV AX,DATA

MOV DS,AX

MOV AL,NUM1

ADD AL,NUM2

MOV SUM,AL

INT 21H

ENDS

END START

Part: B

0100 + 0100 = 1000 (overflow flag is turned on)

1000 + 1000 = 0000 (overflow flag is turned on)

Part: C

0100 + 0001 = 0101 (overflow flag is turned off)

0110 + 1001 = 1111 (overflow flag is turned off)

1000 + 0001 = 1001 (overflow flag is turned off)

1100 + 1100 = 1000 (overflow flag is turned off)

7.2 Write a program in assembly language such that: a. Two binary numbers are saved in two separate memory locations. b. Asthe numbers areadded, an overflow will cCor. c. As the numbers are added, no overflow occurs. 7.2 Write a program in assembly language such that: a. Two binary numbers are saved in two separate memory locations. b.
