WebThe DS:SI (or ESI) and ES:DI (or EDI) registers point to the source and destination operands, respectively. The source operand is assumed to be at DS:SI (or ESI) and the destination operand at ES:DI (or EDI) in memory. For 16-bit addresses, the SI and DI registers are used, and for 32-bit addresses, the ESI and EDI registers are used. Webusing assembly language, create a program that sets the EAX, EBX, ECX, EDX, ESI, and EDI registers as follows. AL=AA. BH=BB. CX=CCCC. EDX=89ABCDEF. ESI=00000000. EDI=FFFFFFFF. use MOV to set these values. be careful the source and destination have to be the same size.
