Форматы обращения к памяти:

	[Rn,#offset12]	
	[Rn,Rm]


	[Rn,#offset12]!		preindexing + update
	[Rn],#offset12		postindexing + update
	                	EA= Rn,	Rn <- Rn + Update
	
	[Rb,+-Rm,shift]		preindex
	[Rn,+-Rm,shift]!	preindeing + update
	[Rn],+-Rm,shift		EA = Rn, Rn <- Rn + Update





  
  Особенности 
 
	Самое популярное ядро для встроеных приложений
	Имеет вариант Thumb с короткими инструкциями.
