Hi guys,
 my name is Vin=EDcius and I'm doing a master degree. My thesis is a simpli=
fied on-board computer for an satellite. I must implement some scheduling a=
nd package analysis functions. As I need to work with a real time system, I=
'm using the zfp flag for compilation. I tried to implement some interrupti=
ons using sentences like this:

   procedure Receive_USART;

   -- Address the interruption handler	=09
   pragma Machine_Attribute (Entity =3D> Receive_USART,
                             Attribute_Name =3D> "signal");

   pragma Export (Convention    =3D> C,
                  Entity        =3D> Receive_USART,
                  External_Name =3D> "__vector_26");    --USART0_RXC

Using Proteus (ISIS Professional 6.7 SP2), I'm debugging the algorithm. The=
 initialization of the interruption is right, but when the interruption occ=
ur, it isn't handling to the procedure.=20

Do I need to do something more to handle the procedure when the interruptio=
n occur ? Do you fellows have any other simple way to handle interruptions =
?

Thanks very much for your help....
