The functions of these parameters are to use AI as DI. When AI is used as DI, the AI state is high level if the AI input
voltage is 7 V or higher and is low level if the AI input voltage is 3 V or lower.
If the AI input voltage is between 3 V and 7 V,the AI state is hysteresis. And then b7-10 is used to determine whether
high level valid or low level valid when AI is used as DI.
The setting of AI (used as DI) function is the same as that of DI. For details, see the descriptions of DI setting.
The following figure takes AI input voltage as an example to describe the relationship between AI input voltage and
corresponding DI state.
