What does 'Z' mean at the end of a net name? I know N means active low

I have a few nets on the Sitara AM6254 that have a z like:
MCU_PORz
MCU_RESETSTATz
PORz_OUT

I know _N or 'bar' over the net name means active low like for resets

But I don't know what z means.

Yes that does help.

Thank you for finding that. I didn't think it would be in the datasheet. should have checked.

Hi,
It is a Tri_State output pin.
In the Z state, it's effectively disconnected open/circuit.
Commonly used on Bus line connected lines.
