Thanks for the file. This datasheet is having more information.
Looking at this datasheet there are three Banks of GPIOs. And I assume that the first bank (GPIO 0 to GPIO27) is available as the 28 GPIOs on the CM4 module.
I also see a statement "The GPIO peripheral has four dedicated interrupt lines. These lines are triggered by the setting of bits in the event detect
status register. Each bank has its own interrupt line with the fourth line shared between all bits."
So that means Bank1 has only one interrupt? And how to set which GPIO of the Bank1 to make it as interrupt and also how to control it to one. I am not clear on this. Any guidance?
