ADC Arithmetic Addition with Carry

Flags affected:

        O D I T S Z A P C  OF: Overflow flag  TF: Trap flag AF: Aux carry
        F F F F F F F F F  DF: Direction flag SF: Sign flag PF: Parity flag
        *       * * * * *  IF: Interrupt flag ZF: Zero flag CF: Carry flag

Examples:

        ADC BX,DI
        ADC EAX,5
        ADC AX,0FFFFH            ;Uses single-byte opcode
        ADC AL,42H               ;Uses single-byte opcode
        ADC BP,17H
        ADC WORD [BX+SI+Inset],5
        ADC WORD ES:[BX],0B800H

Notes:

ADC adds the source operand and the Carry flag to the destination operand, and after the operation, the result replaces the destination operand. The add operation is an arithmetic add, and the carry allows multiple-precision additions across several registers or memory locations. (To add without taking the Carry flag into account, use the ADD instruction.) All affected flags are set according to the operation. Most importantly, if the result does not fit into the destination operand, the Carry flag is set to 1.
