AND Instruction

The instruction AND performs the logical operation "AND", bit for bit.

1. The source is and effective address, the destination is a data register.
2. The source is the data register and the destination is the effective address.

ADDRESS METHODS:	1) Dn, (An), (An)+, -(An), x(An), x(An,xr.s), x.w, x.l, x(PC), x(PC,xr.s), #x
	2) (An), (An)+, -(An), x(An), x(An,xr.s), x.w, x.l

DATA LENGTH: Byte, word, longword

FLAGS:	X - U
	N - S
	Z - S
	C - 0
	V - 0

SYNTAX:	AND <ea>,Dn
	AND Dn,<ea>

EXAMPLE CODE:

AND #%11110000,D0 If D0 contained 00111100, it would then contain 00110000

Use AND to selectively clear bits in the destination. Each bit in the source operand that is 0 will cause the corresponding bit in the destination to be 0. Each bit in the source that is 1 will leave the corresponding bit in the destination unchanged. For example:

SOURCE             0000    0101
DESTINATION        0011    0011
-----------        ----    ----
RESULT             0000    0001
