With legacy interrupts one may easily catch any unintended interrupts and clear they flags. With vectored interrupts, unused vectors point to reset, which may be disastrous in some applications. Would it be possible to implement a 'default' vector for unused interrupt sources (naturally with default value of 0, like it is now) so that one may add a routine, like
Code: Select all
void defaultISR(); iv IVT_DEFAULT;
and all otherwise unused vectors would point to it?
