Appendix B Example for electrical connection
INPUT:
Figure 11 INPUT

Input and GND connection is valid.

The input signal is isolated by optocoupler, which is much safer.

Power supply could be identical to IO power supply or different from it
Note:When the Input is not connected:

Bank 0 is activated if VDDIO is not connected

Bank 15 is activated if VDDIO is connected to the power supply
OUTPUT:
Figure 12 OUTPUT

The outputs use push-pull circuits and support both PNP and NPN modes

High level output is effective.

The output signal is isolated by optocoupler, which is much safer
