Reset pin

Is this an input or output?

The schematic shows it connected directly to the 8095 reset controller and through a 22 ohm resistor to the reset pin of the 5350. Will pulling this low damage the 8095?

it is an input, the 8095 is making a brownout protection, it is disabling the reset after 3.3V is stable.

I went ahead and tried it, worked fine.

The datasheets I find for a 8095 show two flavors, open drain and push-pull. Either it is a open drain or I got lucky and the push-pull survived me shorting it's output.
