Table: Check the Interrupt Status and Disable Interrupts and Table: Read, Write, and Compare Interrupt Types describe the flow to run self-test on the GPIO.

In Table: Check the Interrupt Status and Disable Interrupts, the tasks outline the flow to check the interrupt status for bank 0. If any interrupt is enabled, then disable the particular interrupt (bank 0).
