Caution: During normal operation this
pin must be pulled- up, internally or
externally (external pull-up of 10k
mandatory in noisy environment). This
is to avoid entering ICC mode
unexpectedly during a reset. In the
application, even if the pin is
configured as output, any reset will put
it back in input pull-up.
