Thanks, Linus. > > Duc do you have a datasheet for this GPIO controller? > This controller is simple. We have 3 16-pin sets of GPIO pins (these pins can be configured as part of the Flash controller pins, or as GPIO pins). In GPIO mode, we can configure the pin as output or input. There is no interrupt support for these GPIO pins.
