STM32U0 reference manual inconsistent? (exti lines and nvic)

[christian-enderle]

Hello together,

I'm a little bit confused by the NVIC and EXTI description in the RM0503.

The NVIC vector table says the RTC / TAMP interrupts are combined EXTI lines 19 & 21 (on page 302).

But when looking at the EXTI line connections table (on page 309) the RTC source is on line 28 and TAMP on line 29.
