Can a single stamp BS2 module perform mulip le tasks?

If the 'different reasons a reset had occurred' were from distinct sources,
then you could have the distinct reset sources go to a latch. The reset
sources would also go to a OR gate that would trigger the reset (as
described by Jon Williams). The output of the OR gate would also trigger
the latch to store the state of each of the reset lines.
Once the stamp rebooted, it could read the stored states on the latch and
determine the reason for the reset.
Please let me know if this is not clear. I do not know all of the correct
terminology to use.
