Hola, que tal? he intentado hacer una interrupcion externa por RB1 con con este pic pero no me funciona, sinembargo por RB0 me funciona sin problemas ya le he dado mil vueltas, hasta el punto de generar un nuevo proyecto solo con estas dos interrupiones, y sigue sin funcionar por RB1, alguna idea??
