The symbol "R" represents a register designator that specifies which one of the
registers (including operational registers and general purpose registers) is to be utilized
by the instruction. "b" represents a bit field designator that selects the value for the bit
which is located in the register "R", and affects operation. "k" represents an 8 or 10-bit
constant or literal value.
