family of devices powers the analog comparators off
while not in use. When the comparator is enabled, it
tends to exhibit glitches on the output until it
stabilizes. This condition can cause spurious interrupts
if the interrupts are enabled during this interval. If a

allow these interrupts, the device immediately jumps
to the interrupt code. To avoid problems and
undesirable results, it is recommended that the user
observe the following precautions when enabling the
comparator.
