Right now it is active low. So if the Host Interrupt is enabled, it is always high and pulses low when a cap signal changes state. It seems there is no way to change this on the cap-touch configurations, so I wanted to verify that. Can you not change the polarity of the Host Interrupt signal?

Yes, I checked, the host interrupt polarity is not configurable.

Why do you want to change the polarity of the interrupt. Is there any specific application?

Ok course there is a specific application, why else would I be asking this? It's how the hardware is setup, the signal is connected to a wake pin on a processor that wakes when the signal is high, there is nothing that can be changed on this with current HW. It's a very simple question with a yes/no answer, I do not think it is possible and I just want to get confirmation from Cypress that is the case. It is totally fine if it's not possible.
