NRSTIN and NRSTOUT pins
NRSTIN Pin Input Driver is TTL/LVTTL as for all GP I/Os. A permanent pull-up is present
which is the same as R
NRSTOUT Pin Output Driver is equivalent to the O2 type driver except that it works only as
an open-drain (the P-MOS is de-activated). A permanent pull-up is present which is the
same as R

in noisy environments.
- all negative spikes with a duration less than 150 ns are filtered
- all trains of negative spikes with a ratio of 1/2 are filtered. This means that all spikes with a maximum
duration of 150 ns with minimum interval between spikes of 75 ns are filtered.
Data guaranteed by design, not tested in production.
