Registers a DIO interrupt handler.
void attachIntDio(uint8_t u8pin, E_PIN_INT_MODE mode)
For a pin configured as input beforehand, the first parameter is the pin number for which you want to enable the interrupt, and the second parameter specifies the interrupt direction (rising edge, falling edge).
Descriptions of interrupt handlers and event handlers are done in behaviors.
Example
Sets up an interrupt that triggers when the DIO5 pin changes from HIGH to LOW.
void setup() {
the_twelite.app.use<myAppClass>();
pinMode(PIN_DIGITAL::DIO5, PIN_MODE::INPUT_PULLUP);
attachIntDio(PIN_DIGITAL::DIO5, PIN_INT_MODE::FALLING);
}
void loop() {
;
}

class myAppClass: public mwx::BrdPal, MWX_APPDEFS_CRTP(myAppClasslMot)
{
};

Interrupt handler description for the behavior myAppClass. When an interrupt occurs on DIO5, it toggles the output setting of DIO12, and after the interrupt handler finishes, an event occurs that prints * to the serial port Serial.
