I'm struggling to find any information on how the interrupt outputs on the MMA8452Q accelerometer are driven. I need to know whether they're open-drain or push-pull for example. I've poured through Google and can't find anything pertaining to how the outputs are driven.

How are the INT outputs being driven on the MMA8452Q accelerometer?

They are push-pull, looks like LVCMOS or equivalent. The test conditions were for 500uA, it would be advisable to pull less current than the test conditions.

The datasheet table implies that they are driven both high and low.
