On microcontroller systems like the STM32, interrupts are even more important, ... as defined in the vector table (e.g. RM0090, ... Changed that and now timer/good interrupts are working. Thank you!

This is something that we see a lot across STM32 peripherals, not just for USARTs, but also for timers in particular. Picking the right peripheral for one’s needs can be essential, so knowing ...
