On the IIS328DQ, are the INT pins active high or low?

I am assuming that since they can be configured as push-pull or open drain that they are likely active low, but I would like to confirm this assumption. It seems odd that there is nothing in the datasheet about these pins -- only info about their software configurations

​Hi Mike, you can decide the high/low active status of INT1/2 pin selecting IHL bit in CTRL_REG3 [interrupt CTRL register] (22h) (p. 26 of the datasheet). The default value for this bit is 0, which means "active high". You can also select the Push-pull/open-drain INT1/2 pad status acting on PP_OD bit. Regards
