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.
