I'm using an MCC128 as part of a stack up of various HATs for the Raspberry Pi, and it looks like some kind of plug can slide into the back of the terminal blocks. Using a plug would greatly simplify my deployment.
Is the IRQ pin on the MCC128 necessary for normal operation?

My setup is using an MCC128 hat for general purpose data acquisition, as well as a separate hat for RS485-based sensors. I ran into an issue where the RS485 hat uses the Raspberry Pi's SPI1 interface, which conflicts with the IRQ pin (GPIO20) used on the MCC128. Is the IRQ pin strictly necessary for normal operation? If it is necessary, would it be possible to change which pin is used?
