EXTI pin mapping problem

Question asked by Shannon on Jan 26, 2012

It would seem to me given the way the GPIO pins are mapped to EXTI lines, there is no way to use two pins that have the same GPIO pin number.  For example, in my case I would like to use pins A8 and B8 as separate interrupts.  Since all pins with the designation '8' are mapped to the same line, there does not seem to be a way to configure the AFIO_EXTICR registers.

Am I missing something?  As I look at it, it would seem to preclude using the same pin number twice.  If one number is used on one port that pin is excluded on all other ports!
