NAME	ADD -- Add integer
SYNOPSIS	ADD <ea>,Dn ADD Dn,<ea> Size = Byte, Word, Long
FUNCTION	Source- and destination-operand are added using binary addition. The result is stored in the destination location The size of the operation may be specified as byte, word, or long. The mode of the instruction indicates which operand is the source and which is the destination as well as the operand size.

OP-MODE	Byte Word Long   000 001 010 (Dn) + (<ea>) -> Dn 100 101 110 (<ea>) + (Dn) -> <ea>

RESULT	X - Set the same as the carry bit. N - Set if the result is negative. Cleared otherwise. Z - Set if the result is zero. Cleared otherwise. V - Set if an overflow is generated. Cleared otherwise. C - Set if a carry is generated. Cleared otherwise.
