Use
uncertain
Uses the input value
of IN_1 or IN_2 whose
statusis“Uncertain”
regarding it as a value
of“Good”.

Uses the input value
of IN_1 or IN_2
whosestatusis“Bad”
regarding it as a value
of“Good”.
6 Carry
Carries over an excess
exceeding the threshold
at reset to the next
integration.
(Notethatthisdoesnot
