(11) Absolute Address
When data is accessed by an absolute address, the absolute address value should be placed in the
memory table in advance. That value is transferred to the register by loading the immediate data
during the execution of the instruction, and the data is accessed in register indirect addressing
mode.
With the SH-2A, when data is referenced using an absolute address not exceeding 28 bits, it is also
possible to transfer immediate data located in the instruction code to a register and to reference the
data in register indirect addressing mode. However, when referencing data using an absolute
address of 21 to 28 bits, an OR instruction must be used after the data is transferred to a register.
Table 2.6
(12) 16-Bit/32-Bit Displacement
When data is accessed by 16-bit or 32-bit displacement, the displacement value should be placed
in the memory table in advance. That value is transferred to the register by loading the immediate
data during the execution of the instruction, and the data is accessed in the indexed indirect
register addressing mode.
