Hello,

     I'm writing a software using Blackfin BF512F and I have a question about ports (GPIO) interrupt management.

How can I discriminate wich pin used like GP Input in a port (for example PortF) generates an Interrupt?

In other words, when the ISR is called, how can I know if it is called, for example, from PF4 pin instead PF5 pin?

Thank you very much for your answers

Maurizio
