STM32U5A9NJH6Q: When PB4, PB14, and PB15 are set to EXTI with interruption, EXTI15 interruption is activated by the signal of PB14

Hello , 

I have an issue in STM32U5A9 IN EXTI interruption.
When PB4, PB14, and PB15 are set to EXTI with interruption, EXTI15 interruption is activated by the signal of PB14.
And EXTI15 interruption isn't activated by the signal of PB15.

All EXTI settings are Pull-up and External Interrupt Mode with Rising / Falling edge trigger detection

I do not believe it is a circuit board issue since it is reproduced on both STM32U5A9J-DK and another circuit boards.

Environment : STM32CubeIDE Version: 1.16.0 Build: 21983_20240628_1741 (UTC)

 

Is there any way to resolve this problem?
