the instruction can be restarted after the exception. Note that when a Push
Multiple operation is aborted due to an exception, the memory state is
changed by the stores that have already completed before the exception.
The Stack Pointer must already be 32-bit aligned to use this instruction. If
an unaligned memory access occurs, an exception is generated and the
instruction aborts, as described above.
Only pointer registers
