3. This instruction is not recommended for RF operation.
4. This instruction cannot operate under RF.
The symbol "R" in the instruction set represents a register designation that specifies
which one of the registers (including operational registers and general purpose
registers) is to be utilized by the instruction.
The symbol "b" represents a bit field designator that selects the value for the bit that is
located in the register "R" and affects operation.
The symbol "k" represents an 8 or 10-bit constant or literal value.
