Hi everyone
I have connected a tactile switch at port PB11, which is active low.
I try to enable an interrupt on this port.
I can't see a particular selection of pin PB11.
The port B includes 15 I/O pins and FC7 offers port interrupt only for pins EXTI0, EXTI1, EXTI2, EXTI3, EXTI4, EXTI8, and EXTI13.
Why there is not included the EXTI11? Provided that the PB11 is an I/O port?
Is there any restriction for the rest pins of port B?
Thanks
STM32 Port Interrupt

Hi
The STM32F303RE (QFP64)
Now I'm looking on the datasheet at the SYSCFG_EXTCRIx registers.

Re: STM32 Port Interrupt
The corresponding configuration register for the PB11 is the SYSCFG_EXTICR3 bits 12,13,14,15 (EXTI11).
In the end, is noticed that some IO pins may not be available on small packages.
Is that the case?
Thanks

Re: STM32 Port Interrupt
Could you please try replacing this in the FCD directory ...

Hi Leigh
Yes, it is working flawlessly on my actual hardware.
Thanks a lot
FYI: On the FC7 simulator doesn't work.
