MCF5223x PWOR function ?

The PWOR bits set pins to "wired-OR".

There is no further explanation in the RM.

 

Does anyone know what it does ?

Does it disable the low side driver transistor of the pin ?

Hi Mr Bean

 

I haven't used this function but I believe it is effectively setting open drain output so that several outputs can be connected together. Using a pull-up, any output driving '0' 'wins'.

 

Wired-OR is a little confusing because sometimes it is also called Wire-AND. See the following: Wired-OR

Yes, I think it is what is normally called open-drain output. I haven't tried it though.
