Unformatted text preview: copy CL into DH (b) copy DS into AX (c) move 4EEEH into SI (d) copy the contents of the word in memory pointed to by SI into BX 4. All integers in this problem are written in hexadecimal. Let AX = 19C3, BX = 2B01, CX = 7EE0, DI = 1888, SI = 330, CS = 500, DS = 9FF0, SS = 9876, and the contents of the word in memory to which [SI+770H] points = F809. For each instruction below, (a) identify the addressing modes of both operands, (b) indicate the contents of the destination operand after the addition, (c) give the flag settings for CF, PF, AF, ZF, SF, and OF after the addition, and (d) write the machine code (see Brey, p. 782 for formats). ADD CH, 14H ADD [SI+770H], AX...
