In CubeMX (ver: 4.23 mcu: STM32F427) I'm trying to define two ports PE10 and PB10 as GPIO_EXTI10 (I need to get edge interrupt on either one).
However, in the 'Pinout' view, when I click GPIO_EXTI10 for PB10 and then for PE10, PB10 is erased (the green turn white). Am I trying to do something that is not possible at all or is it only a limitation of CubeMX?Is there another way to do it in CubeMX?

There's no way to do it on the chip, that's why there's no way to do it in CubeMX.
Read the External interrupt/event line mapping subchapter of Interrupts chapter of RM0090.

Only one pin at each index, so can't have multiple Pin#10
Want PB10, PA11, PA12, etc

That was quick... thank you for the reference, I'll read that.
