Dear ST,
I am using the ISM330DLC gyro and accelerometer,
In the electrical connection mode 1 I have a pin called VDDIO.
In my application I connected this pin to 3V but, I don't have any idea what is the use of this pin?
Thank you for explaining

Well, that's in the data sheet, table 1, with the pin descriptions:
VDDIO(1) Power supply for I/O pins
Footnote 1 stands for: Recommended 100 nF filter capacitor.
Does it answer your question?

Hello Peter,
I think that means If I want 4.5v on INT1/2, went the interrupt is triggered, I have to connect VIO to 4.5v?

The data sheet clearly states in Table 3:
Vdd_IO = Power supply for I/O, min 1.62V, max 3.6 V
4.5V are slightly above 3.6V, so they are not permitted.
If you need a different voltage level because the connected components work there, you still have to keep within the voltage range for VDDIO and use a level shifter at INT1 or INT2, for example.
