PART C (25 MARKS) QUESTION 1 a) Which data directive is used when defining 8-bit integers and 16-bit integers? Give an example for each. (4 marks) b) Verify whether the following statements are TRUE or FALSE. The INC instruction does not affect the Carry flag. The MOV instruction requires both operands to be the same size. The DS register can be the destination operand of a MOV instruction. The Overflow flag may be set when adding a positive integer to a negative integer. (4 marks) a) i) ii) iii) iv) QUESTION 2 Write a program segment in an assembly language according to the following expression. Assume TOTAL, DWORD, ALPHA and BETA are 16-bits memory operands. TOTAL = DWORD + (ALPHA BETA) + 1 (3 marks) b) By using SHIFT instruction in assembly language, write a program segment to represent the following instruction. RESULT = ( 256 + 8) + ( 16 / 4 ) (4 marks) PART C (25 MARKS) QUESTION 1 a) Which data directive is used when defining 8-bit integers and 16-bit integers? Give an example for each.
