4.3 Input Wiring
The device can receive external input signal via I/O interface, and here we take type I device and
Line 0 as an example to introduce input wiring.
Note
Input wiring may differ with different types of external devices.

4.4 Output Wiring
The device can output signal to external device via I/O interface, and here we take type I device
Line 3 as an example to introduce output wiring.
Note
●
Output signal wiring may differ with different types of external devices.
●
The voltage of VCC should not higher than that of PWR. Otherwise, the device's output signal
may have exception.
