I'm looking at XMC1200 GPIO block diagram trying to wrap my head around everything.

I'm trying to figure out what the "FF" block is. I don't see any reference to "FF" in the following documentation and all the other blocks align with control registers.

Any idea what the "FF" block is?

I guess it means "Half Bridge".
