Hello,
In the Kinetis K60 uP, the general-purpose-input-output (GPIO) port register PORTx_PCRn, bit ODE called "Open Drain Enable" allows the port to be configured with an "Open Drain Output". Could anyone please explain to me what the significance of Open-Drain is? Schematically speaking, what does the port look like with the "Open Drain" enabled vs. disabled? I'm trying to understand when an application would want an Open-Drain output vs. a non-open-drain.
Thanks and regards,

I think that a standard open-drain description contains this information:
