When a Data Abort occurs, the instruction continues to completion. The ARM9E-S
restores the modified base pointer (which the load activity before the abort occurred
might have overwritten).

STM
During the first cycle, the ARM9E-S calculates the address of the first word to be
transferred, while performing an instruction prefetch and also calculating the new
value for the base register.
During the second and subsequent cycles, ARM9E-S stores the data requested in
the previous cycle and calculates the address of the next word to be transferred.
