NAME
	ROXL, ROXD -- Rotate left with extend and rotate right with extend

SYNOPSIS
	ROXd	Dx,Dy
	ROXd	#<data>,Dy
	ROXd	<ea>
	where d is direction, L or R

	Size = (Byte, Word, Long)

FUNCTION
        A rotation is made on destination operand bits.
        Rotation uses bit X.

	                                                  <ea>

NUMBER/REGISTER
	Specifies number of rotating or number of register which contents
	the number of rotating.
	If i/r = 0, number of rotating is specified in the instruction as
	immediate data
	If i/r = 1, it's specified in the data register.
	If dr = 0, right rotating
	If dr = 1, left rotating

SIZE
	00->one Byte operation
	01->one Word operation
	10->one Long operation

REGISTER
	For a register rotating:
	Indicates the number of data register on which rotating is applied.

	For a memory rotating:
	<ea> indicates operand which should be rotated.
	Only addressing modes relatives to memory are allowed:

RESULT
	X - Set by the last bit out of operand.
            Not changed if rotation is zero.
	N - Set if the result is negative. Cleared otherwise.
	Z - Set if the result is zero. Cleared otherwise.
	V - Always cleared
	C - Set according to the last bit shifted out of the operand.
