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
SB
Operation: If src_bit is set, the following instruction word is skipped.
Note:
SC
Operation: If C is set, the following instruction word is skipped.
Note:

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.

Only one word is skipped by this instruction. To avoid strange results, make sure that any instruction
following SB is a single-word instruction.
