8-bit micro-controller
The symbol "R" represents a register designator which specifies which one of the 64 registers (including
operational registers and general purpose registers) is to be utilized by the instruction. Bits 6 and 7 in R4 determine
the selected register bank. "b'' represents a bit field designator which selects the number of the bit, located in the
register "R'', affected by the operation. "k'' represents an 8 or 10-bit constant or literal value.
