## What the example does * Initializes the driver * Configure a pin as input * Registers an interrupt that logs port value of the INT pin * Blinks, or toggles, P10 output ## Wiring Connect an LED with an appropriate current-limiting resistor to pin P10 of the TCA6424A. Connect buttons between pins P01, P02, and P03 of the TCA9564A and ground. Connect the INT pin of the TCA9564A to a selected GPIO of the ESP32. The GPIO for connecting INT can be chosen in `menuconfig`. See the default settings in `Kconfig.projbuild`.
