(Note 1) Cannot be specified when the operation unit is 16-bit integer (US).
(Note 2) Only 16-bit devices, 32-bit devices, and integer constants can be modified. (Real number constants,
and character constants cannot be specified.)

Outline of operation
● This instruction rotates the data specified by [D] to the right (to the low bit position), by the
number of bits specified by [n] (decimal specification), with SR9 (CY).
● Only the lower 8 bits in data are available for [n]. The rotation amount is specified between 0
and 255 bits.
● (Rotation amount - 1) bits are output to SR9 (CY).
● When the operation unit is 16 bits (US), if [n] is either 0 or a multiple of 17, the rotation
amount is regarded as 0, and this instruction is not executed.
● When the operation unit is 32 bits (UL), if [n] is either 0 or a multiple of 33, the rotation
amount is regarded as 0, and this instruction is not executed.
