TPS65987D: What settings to make sink compatible with old school 5V charger too?

TPS65987D: How to activate GPIOs based on charging status

This thread is based off the previous one where I asked how to do charging in both USB-C PD and in old 5V usb charger.  I solved that but, ...

I'm still having a bit of an issue on this. I need a GPIO signal that goes to my charger. I've tried many of the mapped events but none seems to do what I need. I need to be able to tell my charger when to enable and have it work in both USB-C where a PD contract is negotiated and when we are connected to a old USB charger. Right now I can't get one signal. It almost needs to be PP1 switch closed AND acting as a sink. Is there anything like that?

Thanks,

C
