Chapter 9 considered some differences between instructions that are inherently addressed and those that are not. Inherently addressed instructions generally require fewer machine cycles and save program storage space because they have no operands. Since this chapter considers all the various modes of addressing available to users and programmers of MPUs, it is convenient to recapitulate on the SIMNIC instructions already described.
