RL        fr                Rotate fr left


Words:        1        Cycles:        1                Affects:        C

 

Operation:        Fr is rotated left. On entry, C must hold the value to be shifted into the least-significant bit of the fr value.  On exit, C will hold the previous most-significant bit of the fr value.
