Hello,
I cannot find any detail about the output type of INT1 pin in the ISM330DHCX datasheet.
From what I read about the registers configuration about this pin, I thought that would be a push-pull output, but if I configure an external 10K pull-up to 3.3V I see that the signal is fixed to 1.2V
I already found the note about the initialization procedure that depict not to set any pull-up (so I'm removing that), but this behavior is not explained by a simply output pin.
Is maybe this also a bootstrap input for internal use?
For the use with the linux driver st_lsm6dsx (that has this component's compatible) should I set a pull-down or leave the control only to the ISM330DHCX?
Best regards,
Rosario

The function of pin INT1 is described in the data sheet:
INT1_CTRL (section 9.9) manages the signals that are output by ORing
CTRL3_C (section 9.14) describes at which level INT1 is active (H_LACTIVE) and whether INT1 works as push-pull or open drain.
Does it answer your question?
