34.2.4.3 LDR and STR, register offset
Load and Store with register offset.
op{type}{cond} Rt, [Rn, Rm {, LSL #n}]
where:
op is one of:
type is one of:
cond is an optional condition code, see
Rt is the register to load or store.
Rn is the register on which the memory address is based.
Rm is a register containing a value to be used as the offset.
LSL #n is an optional shift, with n in the range 0 to 3.
LDR instructions load a register with a value from memory.
STR instructions store a register value into memory.
The memory address to load from or store to is at an offset from the register Rn. The
offset is specified by the register Rm and can be shifted left by up to 3 bits using LSL.
The value to load or store can be a byte, halfword, or word. For load instructions, bytes
and halfwords can either be signed or unsigned. See
alignment”.
In these instructions:
When Rt is PC in a word load instruction:
•
•
•
•
LDR: Load Register.
STR: Store Register.
B: unsigned byte, zero extend to 32 bits on loads.
SB: signed byte, sign extend to 32 bits (LDR only).
H: unsigned halfword, zero extend to 32 bits on loads.
SH: signed halfword, sign extend to 32 bits (LDR only).
—: omit, for word.
Rn must not be PC
Rm must not be SP and must not be PC
Rt can be SP only for word loads and word stores
Rt can be PC only for word loads.
