Off
The pin is not powered by suspend supply and is valid under main power only.
Hi-Z
The pin is powered, but tri-stated either because the pin is open-drain or VCC function is selected on VTR
powered pin. The pin requires external pull-up when tri-stated.
Active
The pin is powered and active high.
Running
The input clock is powered and running.
Input
The pin is powered and driven by external circuitry to high or low level.
Out
The pin is powered and driven to high or low level by the part.
