FDCAN interrupt lines in the manual...

[Tobe]

I got a hard time comprehending about the two interrupt lines in the manual.

I can really see a "connection" between certain sources to the interrupt lines, nor can i find a register to connect them.

It seems to me, that i only can decide what interrupts will fire, and what interrupt line they will go to then. But i cant think of, how i could have both interrupt lines running in paralell.

I think i missed something.

Is there a better information about this out there?

Absolutely, something wrong with documentation, RM0440 particularly.

Documentation became much worse with new series of microcontrollers, pushing developer to use HAL library only.

There are no even a "tree" of interrupts connection, like it was for STM32F407, for example.
Futhermore there are no any intelligible explanation in documents (STM32H7xx Reference Manual which has similar FDCAN module, User manuals, App Notes etc., etc.).

It is really a sad development, as HAL is a big and ugly beast. Im so glad i do this without any pressure as a hobby. But maybe one day i will find a job as a technical documentation interpreter for STM32 products ;-).
