Question

Please print your name 니 r. Name register D after executing the code? e, what is the value of a Forthe following code sequence, what is the value of re Ida Array+1 looo loo Idab Array+2 1000lo Array equ $1000 A4,aba AA-B 18 Address Data memory oC #1000| $8D 01( 063 Sl

Answer 1

initially a will be loaded with 1001 value that is 6E

b will be loaded with A4

aba performs a+b and stores in a

6E + A4 = 112

E+ 4 = 12 so 1 is carried forward. then 6+A = 10 and 1 carry so 11

next instruction loads 0C in b

sba performs a= a-b

a initially contains 112 b has 0C

a-b will give 112-0C = 106

D contains value 106
