Just a quick note on something I noticed the other day. This sort of ties
in with the recent discussions of PIC firmware behaving unexpectedly in
windowed & non-windowed devices if a programmer forgets to initialise
registers before using them.
I was taking a photograph of a piece of prototype equipment which used a
C54 JW part with the window uncovered (firmware was still being
'improved' !). The equipment was operating at the time. The instant the
flash fired the PIC reset - in fact it underwent a full power on reset as
the TO & PD bits were being checked. This effect appears to be very
repeatable and also occurred on a C57 - JW part with the window uncovered.
I don't know if this effect is of any use and I haven't checked if the
flash affects any other registers etc., but it is probably something to
be aware of.
