What kind of output drive is HRESET_REQ?

A question came up about the HRESET_REQ pin on the P1022. We’re wondering what kind of output driver this is – is it an open drain? We’ve currently got it connected in parallel with our reset button, which has been working fine, but we’re worried that if it is driving high then we will short it to ground when we push the button. So far there’s been no damage, but I just want to make sure I don’t need to make a change on our board.  I’m moving ahead with it designed how I have it, it seems to work fine, but I would love to double check my assumption.

 

Thanks,

 

Adam
