Note: * The assembler of Renesas Technology uses the value after scaling (×1, ×2, or ×4) as
the displacement (disp).
Description: This instruction stores immediate data, sign-extended to longword, in general
register Rn. In the case of word or longword data, the data is stored from memory address (PC + 4
+ displacement × 2) or (PC + 4 + displacement × 4).
With word data, the 8-bit displacement is multiplied by two after zero-extension, and so the
relative distance from the table is in the range up to PC + 4 + 510 bytes. The PC value is the
address of this instruction.
With longword data, the 8-bit displacement is multiplied by four after zero-extension, and so the
relative distance from the operand is in the range up to PC + 4 + 1020 bytes. The PC value is the
address of this instruction. A value with the lower 2 bits adjusted to B'00 is used in address
calculation.
Notes: If a PC-relative load instruction is executed in a delay slot, a slot illegal instruction
exception will be generated.
