Hi, I'm working with an MCU that has 4 interrupts on external PINs, and I wish to interrupt on an active low input. However, 3 of the interrupts are active high interrupt while the last one, though it's an active low interrupt, is also labelled a non-maskable interrupt. I want to be able to mask the interrupt since I don't want it enabled all the time. Other than using an inverter, is there a way I can convert an active high to an active low interrupt?
Thanks.
