An SPI interface provides multiple programming options. Users can configure polling time and polling active time to conserve power between monitoring events. They can also program wetting current, interrupt capability, and switch configuration (i.e., battery connected or ground connected). The programmable wetting current (0mA to 15mA) is applied to any closed switch to clean switch contacts that are exposed to adverse conditions.
