Writing a 1 enables
Comparator0 as a reset
source (active-low).
Writing a 1 forces a sys-
tem reset.
Writing a 1 enables the
Missing Clock Detector.
The MCD triggers a reset
if a missing clock condition
is detected.
Writing a 1 enables the
V
source.
Writing 1 to this bit
before the V
is enabled and stabilized
may cause a system
reset.
