Caution: During normal opera-
tion this pin must be pulled- up,
internally or externally (external
pull-up of 10k mandatory in noisy
environment). This is to avoid en-
tering 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.
