■Input value increment operation processing
In input value increment operation processing, the following processing is performed for the input value (E1).
e1 e2
0 0
0 1
1 0
1 1
■Integration value calculation processing
In integrated value calculation processing, the following processing is performed for the input value increment (T1).
e1 e2
0 0
0 1
1 0
1 1
*1 In the case of integration stop/reset (e1 = 0), processing is performed by assuming it as integration hold clear (e2 = 0).
■Output conversion processing
In output conversion processing, the following processing is performed for the integrated values (T2, T3).
SUMPTN Condition
T2  HILMT
0
Others
T2  HILMT
