Caution: During normal oper-
ation this pin must be pulled-
up, internally or externally (ex-
ternal pull-up of 10k mandato-
ry 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 in-
