Since GPIO bus is 16-bit wide, the max data size shall be 16 bits as well. GPIO interrupts require the programmer to clear the interrupt with GPIO_INT_Clear() at the end of the ISR while EXTI Interrupt automatically leaves the ISR as soon as the interrupt condition becomes false. In the exception table, they start from address 0x00000004 and are numbered. On the other Hand, CubeMX isnt perfect and it might not have the interrupt on the pins you want well implemented. What is it that defines which interrupt the GPIO pin will trigger? I can't find it in the reference. Hi guys, I follow this article : "Interfacing with other hardware peripherals".
