Inputs func-
tions
Mean value processing Stores the last “n” data conversions in the buffer, and stores the mean value of
the conversion values.
Buffer number: n = 2, 4, 8, 16, 32, 64
Peak value holding Stores the maximum conversion value while the Peak Value Hold Bit is ON.
Input disconnection detec-
tion
Detects the disconnection and turns ON the Disconnection Detection Flag.
