42 / 509 page  RENESAS21 Table 2.6 Absolute Address Accessing Classification CPU of SH7000 Series Conventional CPU Absolute address MOV.L @(disp,PC), R1 MOV. B @R1, R0 ......... .DATA.L H'12345678 MOV.B @H'12345678, R0 Note: The address of the immediate data is accessed by @(disp, PC). 16/32-Bit Displacement: When data is accessed by 16-bit or 32-bit displacement, the pre-existing displacement value is placed in the memory table. By loading the immediate data when the instruction is executed, that value is transferred to the register and the data is accessed in the indirect indexed register addressing mode. Table 2.7 Accessing by Displacement Classification CPU of SH7000 Series Conventional CPU 16-bit displacement MOV.W @(disp, PC), R0 MOV.W @(R0, R1), R2 ......... .DATA.W H'1234 MOV.W @(H'1234, R1), R2 Note: The address of the immediate data is accessed by @(disp, PC). |
