Question

1. Write a code segment that adds the immediate values $29 and S42, with the final result located in register A. Determine the value of the result. 2. Write a code segment that uses one instruction to add to register B. 3. Write a code segment that uses one instruction to subtract 1 from register X 4. Write a code segment that loads the value $1234 into register D.

Answer 1

ANSWER 1) a code segment that adda immediate valuca 29 and us. MUI A, 29 => CALL 00101001 (29). MUT B, us >> (8)< 0100 oolo Coe). Add B > (A){-(A) & (B). so, CA)CH anatruction a) a code segment that Unea one to add 1 to reginter B. MVI A, I >> CAF 0001 CI). Adds >> CAL CA) +CB). les CAK I+CB). if (8) = 0100 CM). So , ce)<- bool + 000 (A) 0101(5). 3) a code segment to subntact from one anotruction that Unea regintea X.

code to substract I from regenter & MOV A, X => CASE CX) => CA ) -CAD-1 Cold CA) <(*)-1. 4) A Code segment that load the value $1234 into register o. code to load vawe 123u an regenter D. 1234 as an immediate numea that can be store an 8-bit register So, . Moz, 1 2 34 = Ce)<-( : 34). Move D, A =) CO< (A) Cor) (o)t (1234).
