gpio_add_raw_irq_handler_masked64() function

Adds a raw GPIO IRQ handler for the specified GPIOs on the current core In addition to the default mechanism of a single GPIO IRQ event callback per core (see gpio_set_irq_callback), it is possible to add explicit GPIO IRQ handlers which are called independent of the default event callback. This method adds such a callback, and disables the "default" callback for the specified GPIOs. A raw handler should check for whichever GPIOs and events it handles, and acknowledge them itself; it might look something like: \code{.c} void my_irq_handler(void) { if (gpio_get_irq_event_mask(my_gpio_num) & my_gpio_event_mask) { gpio_acknowledge_irq(my_gpio_num, my_gpio_event_mask); // handle the IRQ } if (gpio_get_irq_event_mask(my_gpio_num2) & my_gpio_event_mask2) { gpio_acknowledge_irq(my_gpio_num2, my_gpio_event_mask2); // handle the IRQ } } \endcode
