RL
Operation: dest is rotated left one bit. On entry, C must hold the value to be shifted into the least-significant bit of
RR
Operation: dest is rotated right one bit. On entry, C must hold the value to be shifted into the most-significant bit of

the dest value. On exit, C will hold the previous most-significant bit of the dest value. The MOV W,<<fr
command is similar to RL fr, except the result is moved to W, and fr keeps its original contents.
