Range =
Division is performed with the result truncated below the decimal point.
The disable time is set for each range as follows:
Note The AF operation disable time for range B is set as follows:
(Input value of SMT_A/B pin - Input value of SMT_B/C pin)
(S • M reading - Input value of SMT_B/C pin)
S • M reading range
