n-bit rotation
 Specify any of "0" to "15" as "n". If the value specified as "n" is "16" or greater, operations will be as follows:
- When "n" is "16", the value becomes the one when 16-bit rotation was executed.
- When "n" is "17" or above, the value of D becomes indefinite.
RCR
 Rotates 16-bit data of the device designated by "D", including carry flag, n bits to the right.
The carry flag is ON or OFF depending on the status prior to the execution of the RCR instruction.
