Hi,

I'm working on stm32f410RB Nucleo board and I have to set interrupt on pins PB11 and PC11 but on CubeMX project setting one pin exclude the other one interrupt, why?

I have to configure it manually or is an hardware problem?

N pin can be set as interrupt only on one port.

PB11 and PC11 can be in the same time interrupts.

RTFM

It is a comprehension problem, the functionality is documented to support a single slot across all banks, if you use Slot 11 for PB11 you can't also use it for PC11, you'd need to use PC10 or PC12

This should be diagrammed in the Reference Manual, review.
