Function Documentation

IntDefaultHandler()

static void IntDefaultHandler ( void  )

static

The default interrupt handler.

This is the default interrupt handler for all interrupts. It simply loops forever so that the system state is preserved for observation by a debugger. Since interrupts should be disabled before unregistering the corresponding handler, this should never be called.

Returns

None
