7-9-6 A/D Conversion Value

When a signal is input that exceeds the allowed ranges indicated below, the conversion value will be processed as it is. However, inputting out-of-range signals may result in hardware failure or system malfunction, so do not input out-of-range signals.

Note If a voltage exceeding the input voltage limits is input, the conversion value will be either the upper or lower limit value.
