The value to load or store can be a byte, halfword, word, or two words. Bytes and
halfwords can either be signed or unsigned. See

For load instructions:
When Rt is PC in a word load instruction:
For store instructions:
These instructions do not change the flags.

[Rn, #offset]
Pre-indexed addressing
The offset value is added to or subtracted from the address obtained from the register
Rn. The result is used as the address for the memory access and written back into the
register Rn. The assembly language syntax for this mode is:
[Rn, #offset]!
Post-indexed addressing
The address obtained from the register Rn is used as the address for the memory
access. The offset value is added to or subtracted from the address, and written back
into the register Rn. The assembly language syntax for this mode is:
[Rn], #offset
Rt can be SP or PC for word loads only
Rt must be different from Rt2 for two-word loads
Rn must be different from Rt and Rt2 in the pre-indexed or post-indexed forms.
bit[0] of the loaded value must be 1 for correct execution
a branch occurs to the address created by changing bit[0] of the loaded value to 0
if the instruction is conditional, it must be the last instruction in the IT block.
Rt can be SP for word stores only
Rt must not be PC
Rn must not be PC
Rn must be different from Rt and Rt2 in the pre-indexed or post-indexed forms.
