Section 6 Instruction Descriptions
6.1.28
Format
LDRE @(disp,PC) disp
Description: Stores the effective address of the source operand in the repeat end register RE. The
effective address is an address specified by PC + displacement. The PC is the address four bytes
after this instruction. The 8-bit displacement is sign-extended and doubled. Consequently, the
relative interval from the branch destination is –256 to +254 bytes.
Note: The effective address value designated for the RE reregister is different from the actual

repeat end address. Refer to table 4.35, RS and RE Design Rule, for more information.
When this instruction is arranged immediately after the delayed branch instruction, PC
becomes the "first address +2" of the branch destination.
