RM0360 and stm32f030xc.h TIM7 IRQ discrepancy

[Haruki]

I am designing a board based around the STM32F030RC, and noticed an apparent discrepancy on IRQ18 between materials.

STM32CubeMX allows both TIM6 and TIM7 to generate interrupts, and the stm32f030xc.h file it generates defines TIM6 as IRQ17 and TIM7 as IRQ18. However, the RM0360 Reference Manual claims that IRQ18 is Reserved, and does not list an interrupt for TIM7, only for TIM6.

My question is: is IRQ18 generated by TIM7 like STM32CubeMX claims or is it Reserved like RM0360 claims?

Hello @Haruki 

After discutient with the concerned person, I can confirm that the IRQ18 is the TIM7 IRQ, so, I've created the internal ticket number 191296 for correction on the coming releases of the Doc RM0360.

Best Regards.
