I want to use the interrupt number 8 (Radio Frecuency). What is the way for working with this interrupt? Because I cannot work with this interrupt and I was working good with a digital interrupt. My idea is when I have a RF interrupt, I want to change a boolean variable for get in inside one comparation (if variable = true ). I saw that into radioeng.c there is a ready interrupt (Ext_Int8_Handler) but I cannot change the value of variable that there is other code.
