ASL Instruction

Performs an arithmetic shift to the right on a data register or a memory location. There are three possibilities:

1. Shift a data register to the left. Number of steps is stored in another data register.
2. Shift a data register to the left. Number of steps is an immediate value. Shift range 1-8 bits.
3. Shift a word in the memory one bit to the left.

ADDRESS METHODS: 3) (An), (An)+, -(An), x(An), x(An,xr.s), x.w, x.l

DATA LENGTH: Byte, word, longword

FLAGS:	X - The last bit that was sent out of the operand. Unaffected if number of steps is 0.
	N - S
	Z - S
	C - Same as X
	V - Set if the most significant bit was changed during the operation, otherwise it is cleared.

SYNTAX:	ASL Dx,Dy
	ASL #<data>,Dy
	ASL <ea>

EXAMPLE CODE:

ASL.B #1,D0 if D0.B contained 00001111, it would now be 00011110
