void ExecuteHandler (INT_HANDLER Handler);

Executes an interrupt handler.

ExecuteHandler executes the interrupt handler pointed to by Handler. The only purpose of this function is to allow calling the previous interrupt handler (usually the default one) from the user-defined interrupt handler. This function must not be executed from anywhere out of the user-defined interrupt handler (defined using DEFINE_INT_HANDLER). Otherwise, you will get the "Privilege Violation" crash, because all interrupt handlers expect to be executed in the supervisor CPU mode. Parameter Handler should be either the value returned from GetIntVec, or the address of a user-defined interrupt handler defined using DEFINE_INT_HANDLER. It must not be the address of an ordinary C function. See DEFINE_INT_HANDLER for an example of usage.
