3.3.4. Address alignment

An aligned access is an operation where a word-aligned address is used for a word, or multiple word access, or where a halfword-aligned address is used for a halfword access. Byte accesses are always aligned.

There is no support for unaligned accesses on the Cortex-M0+ processor. Any attempt to perform an unaligned memory access operation results in a HardFault exception.
