gpio_set_irq_enabled() function

Enable or disable specific interrupt events for specified GPIO This function sets which GPIO events cause a GPIO interrupt on the calling core. See gpio_set_irq_callback, gpio_set_irq_enabled_with_callback and gpio_add_raw_irq_handler to set up a GPIO interrupt handler to handle the events. Events is a bitmask of the following gpio_irq_level values: bit | constant | interrupt ----|---------------------|------------------------------------ 0 | GPIO_IRQ_LEVEL_LOW | Continuously while level is low 1 | GPIO_IRQ_LEVEL_HIGH | Continuously while level is high 2 | GPIO_IRQ_EDGE_FALL | On each transition from high to low 3 | GPIO_IRQ_EDGE_RISE | On each transition from low to high which are specified in gpio_irq_level
