Documentation: USART1/2 and APB2/1 on STM32U5 series

Is USART1 on APB1 (AN5593, tab.17) or APB2 (DS, RM, CubeMX) and USART2 on APB1 (DS, RM, CubeMX) or APB2 (AN5593, tab.17)? Guess, there is an issue in an5593-how-to-use-the-gpdma-for-stm32u5-series-microcontrollers-stmicroelectronics Rv.4 , isn‘t it?

Hello @FB1, 

As @TDK already said, the RM and DS are correct.

The RM/DS is correct.

When in doubt, you can go into the code and look at the memory address of USART1 and USART2 to see which one they're in.
