[C\u00f3mo] Agregue dc_wake_and_execute_gpint() para ajustar la secuencia de activaci\u00f3n, ejecuci\u00f3n y suspensi\u00f3n. Si GPINT se ejecuta correctamente, DMCUB volver\u00e1 a entrar en modo de suspensi\u00f3n despu\u00e9s de que se devuelva la respuesta opcional. Funciona de manera similar a la interfaz de comando de la bandeja de entrada."
