| NAME | ROXL, ROXR -- Rotate left with extend and rotate right with extend | 
| SYNOPSIS | 
where d is direction, L or R| ROXd | Dx,Dy |  | ROXd | #<data>,Dy |  | ROXd | <ea> |  Size = (Byte, Word, Long)
 | 
| FUNCTION | A rotation is made on destination operand bits.
Rotation uses bit X.

| 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. |  |
