The data from file register F is placed in the ALU and the RRF/RLF
operation is performed. File register F at this point has not been
altered. If the destination bit = 1 then the new data from the ALU is
placed back into file register F. If the destination bit = 0, then
the new data from the ALU is placed into the W register. The carry bit in
the status register will also be changed.
