ADC adds the operands, adds 1 if the Carry Flag is set, and places the
resulting sum in destination. Both operands may be bytes or words, and
both may be signed or unsigned binary numbers.
Note: ADC is useful for adding numbers that are larger
than 16 bits, since it adds a carry from a previous
operation.
