Offsets are measured in -bytes. These instructions do not affect the condition flags. - -Register Store --------------- - -* str(Rt, [Rn, imm7]) ``[Rn + imm7] = Rt`` Store a 32 bit word -* strb(Rt, [Rn, imm5]) ``[Rn + imm5] = Rt`` Store a byte (b0-b7) -* strh(Rt, [Rn, imm6]) ``[Rn + imm6] = Rt`` Store a 16 bit half word (b0-b15) - -The specified immediate offsets are measured in bytes.
