Figure 6.1, Figure 6.2 and Figure 6.3 show the fault checking sequence for translation table managed TLB modes.
The condition for the alignment fault shown in Figure 6.3, for both Section and Page cases, is that all of the following apply:
MMU on
U=1
Strongly ordered or device
Unaligned access.
If all of these apply, the check aborts with an alignment fault.
