I am planning to use MC33972 in my application. However while evaluating i found that for momentary-push-to-on switches the IC generates two interrupts - one for switch closure and other for when you release it.
The only way to prevent this from happening is to disable the IRQ generation at the MC33972 in the handler, read the switch status and re-enable the handler.
The application has two kinds of interactions with the switches - short press and long press, i.e. A single switch must be used for short press and long press with different handlers for each event.
My Q therefore is this - Is it even possible with this IC ?
Are there any application notes on using this IC?
