Logical AND

NAME
	AND -- Logical AND

SYNOPSIS
	AND	<ea>,Dn
	AND	Dn,<ea>

	Size = (Byte, Word, Long)

FUNCTION
	Performs a bit-wise AND operation with the source operand and
	the destination operand and stores the result in the destination.
	The size of ther operation can be specified as byte, word, or long.
	The contents of an address register may not be used as an operand.

REGISTER
	One of the 8 datas registers
	If <ea> is source, allowed addressing modes are:

	--------------------------------- -------------------------------
	|Addressing Mode|Mode| Register | |Addressing Mode|Mode|Register|
	|-------------------------------| |-----------------------------|
	|      Dn       |000 |N reg. Dn| |    Abs.W      |111 |  000   |

	|     (An)+     |011 |N reg. An| |   (d8,PC,Xi)  |111 |  011   |
	|-------------------------------| |-----------------------------|
	|    -(An)      |100 |N reg. An| |   (bd,PC,Xi)  |111 |  011   |

	|([bd,An,Xi]od) |110 |N reg. An|
	|-------------------------------|
	|([bd,An],Xi,od)|110 |N reg. An|
	---------------------------------

	If <ea> is destination, allowed addressing modes are:

	--------------------------------- -------------------------------
	|Addressing Mode|Mode| Register | |Addressing Mode|Mode|Register|
	|-------------------------------| |-----------------------------|
	|      Dn       | -  |     -    | |    Abs.W      |111 |  000   |

	|-------------------------------| |-----------------------------|
	|    -(An)      |100 |N reg. An| |   (bd,PC,Xi)  | -  |   -    |

	|([bd,An,Xi]od) |110 |N reg. An|
	|-------------------------------|
	|([bd,An],Xi,od)|110 |N reg. An|
	---------------------------------
	AND between two datas registers is allowed if you consider the
	syntax where Dn is at destination's place.

	If you use this instruction with an immediate data, it does the
	same as instruction ANDI.
	

RESULT
	X - Not affected
	N - Set if the most-significant bit of the result was set. Cleared
	    otherwise.
	Z - Set if the result was zero. Cleared otherwise.
	V - Always cleared.
	C - Always cleared.
