The result of the addition is assigned to the first operand (DEST), and the flags are set accordingly. ADC is usually executed as part of a multi-byte or multi-word addition operation. When an immediate byte value is added to a word or doubleword operand, the immediate value is first sign-extended to the size of the word or doubleword operand. Flags Affected OF, SF, ZF, AF, CF, and PF as described in Appendix C Protected Mode Exceptions #GP(0) if the result is in a nonwritable segment; #GP(0) for an illegal memory operand effective address in the CS, DS, ES, FS, or GS segments; #SS(0) for an illegal address in the SS segment; #PF(fault-code) if page fault Real Address Mode Exceptions Interrupt 13 if any part of the operand would lie outside of the effective address space from 0 to 0FFFFH Virtual 8086 Mode Exceptions Same exceptions as in Real Address Mode; #PF(fault-code) for a page fault
