EXTINTn is an open-drain output type buffer, fail-safe IO. The recommendation is to connect an external pullup resistor when a PCB trace is connected to the pad and an external input is not being actively driven. Open-drain output type buffer IO has slew rate specified when the IO is pulled up to 3.3V. An RC is recommended for limiting the slew.
