hello everyone , i am trying to learn external interrupt in stm32f407vg controller. i have read in many tutorials that "only lines 0 to 4 have own IRQ handler and lines 5-9 have the same interrupt handler and this is also for lines 10 to 15" .

But in the Reference manual of stm32F407 it is given in page 374 vector table that there are only 5 external interrupt handlers in stm32F407 controller which is confusing .

have i missed anything ?

where is it given that line 5 to 9 and line 10 to 15 have same interrupt handler ?

Thanks in advance .

Thanks

Why have not they written anything about this in the datasheet of stm32F407 or reference manual ?

Is there any other reference manual dedicated for Complete vector table ?

Did you ever review page 375/376, specifically position 23 and 40?
