1.1. Inherent Addressing Mode
This is a mode that needs no address field at all. The operand is specified implicitly in the definition of the
operation code. This mode is used to instructions which operate on registers(A,X,Y,PSW,SP). This mode
has an important advantage that executes faster than any two- or three-byte instruction.
