3.2
Addressing modes and effective address calculation methods are shown in table 3.2. When a
location in virtual memory space is accessed (AT in MMUCR = 1), the effective address is
translated into a physical memory address. If multiple virtual memory space systems are selected
(SV in MMUCR = 0), the least significant bit of PTEH is also referenced as the access ASID. For
details, see section 7, Memory Management Unit (MMU).

Effective Address Calculation Method
Effective address is register Rn.
(Operand is register Rn contents.)
Effective address is register Rn contents.
Effective address is register Rn contents.
A constant is added to Rn after instruction
execution: 1 for a byte operand, 2 for a word
operand, 4 for a longword operand, 8 for a
quadword operand.
